Which of these options best describes backtracking, in a maths sense? 1.Re-writing an equation to remove all the variables. 2.Walking backward while appearing to move forward. 3.Drawing a flow chart with the boxes arranged vertically. 4.Working backward along a flow chart to solve an equation.

1. Re-writing an equation to remove all the variables.

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.
