Full Answer
How do you solve two step inequalities step by step?
Step 2: Multiply or divide both sides of the inequality by the coefficients of the variable. Keep simplifying both sides of the inequality until only the variable is left on one side. To solve two-step inequalities, identify which two operations are involved and use their inverse.
What does it mean to solve inequalities?
Our aim is to have x (or whatever the variable is) on its own on the left of the inequality sign: We call that "solved". Subtract 2 from both sides: Solved! Solving inequalities is very like solving equations ... we do most of the same things ... ... but we must also pay attention to the direction of the inequality.
How do you find the coefficient of an inequality?
Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions. Step 2 Simplify by combining like terms on each side of the inequality. Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other. Step 4 Divide each term of the inequality by the coefficient of the unknown.
How do you solve inequalities with left and right sides?
When we swap the left and right hand sides, we must also change the direction of the inequality: We can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra ), like this:

How to simplify an inequality?
Step 2 Simplify by combining like terms on each side of the inequality. Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other. Step 4 Divide each term of the inequality by the coefficient of the unknown. If the coefficient is positive, the inequality will remain the same.
What happens when the same quantity is added to each side of an inequality?
If the same quantity is added to each side of an inequality, the results are unequal in the same order.
How to solve a literal equation for one letter in terms of the others?
Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions. Step 2 Simplify by combining like terms on each side of the inequality.
When you multiply by a negative number, do you change the direction of the inequality symbol?
This is the only difference between solving equations and solving inequalities. When we multiply or divide by a positive number, there is no change.
What does the inequality symbol represent?
Use the inequality symbol to represent the relative positions of two numbers on the number line.

How to solve inequalities?
Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
Why do inequalities not change?
Because we are multiplying by a positive number, the inequalities will not change.
What If I Solve It, But "x" Is On The Right?
No matter, just swap sides, but reverse the sign so it still "points at" the correct value!
Why do inequalities change when multiplying?
Because we are multiplying by a positive number, the inequalities don't change: Now divide each part by 2 (a positive number, so again the inequalities don't change): Now multiply each part by −1. Because we are multiplying by a negative number, the inequalities change direction . And that is the solution!
Does adding and subtracting affect inequality?
And that works well for adding and subtracting, because if we add (or subtract) the same amount from both sides, it does not affect the inequality. Example: Alex has more coins than Billy. If both Alex and Billy get three more coins each, Alex will still have more coins than Billy.
Can you divide by a variable to solve an inequality?
Do not try dividing by a variable to solve an inequality (unless you know the variable is always positive, or always negative).
How to solve two step inequalities?
To solve two-step inequalities, isolate the variable on one side. This is done using the inverse operations of addition or subtraction and multiplication or division.
What is a two step inequality?
Two-step inequalities are the inequalities consisting of one variable and any two operations. They also require exactly two steps to obtain the solution.
Why is it good to plug a value from the solution set in the inequality?
It’s always a good idea to plug a value from the solution set in the inequality to check if the solution is right.
Which operations should be performed in inverse operations?
Since this inequality involves subtraction and multiplication, we should perform the inverse operations: addition and division respectively.
When multiplying or dividing by a negative number, do we need to flip the inequality sign?
Remember when multiplying or dividing by a negative number, we need to flip the inequality sign.
