How do simple equations work?
Simple equations can be used to solve problems in real-life situations as well. The application of simple equations depends on the situation wherein we need to form the equation ourselves and find the value of the unknown variable. We face such situations while purchasing items at a shop, calculating age problems, finding the missing numbers, guessing the unknown numbers and calculating the speed or time of the train and so on. We translate the situations in the form of equations. We develop strategies in the form of equations to solve these problems. For example, if a child wants to purchase 10 pencils and a box that together cost $35, the cost of one pencil can be assumed as x and the cost of one box can be assumed as y and the equation could be acquired as 10x + y = 35.
