Step-by-step explanation:

Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.

In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.

The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.

<h3>What is a linear equation?</h3>

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The total money = $2 = 200 cents

Types of coins are dimes and quarters

Number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation

$10x + 25y = 200\\x = (y+13)\\10(y+13) +25y= 200\\10y + 130 +25y = 200\\\\35y + 130 = 200\\y = 70/35 = 2$
