### Question

Solving linear equations in one variable has been described as the process of "undoing" or "reversing" all the math that has been done to the variable? Can you explain why this is true? Give an example of solving a simple equation, and explain how your steps are in a sense "reversing" the math.

### Solution

xxxxxxxxx equations xxx xxxxxx xx solve--or xxxxxxxxx for xxx xxxxxxxx (xxxxxxy x). xx equation xxxxxxxxxx x xxxxxxxxxxxx phrase xx operations xxxxxx xx x--xxxxx operations xxxxxxxxy being xxxxxxxx, xxxxxxxxxxx, xxxxxxxxxxxxxx and xxxxxxxx. They xxx xxxx xxxxxxx squaring xxx cubing, xxx xxxxxxx. xxx phrase xxxxxxxxxxy tells yxx xxx xxxxx of xxxxxxxxxx. You xxx xxxxx xx calculating xxx x xx xxxxxxxxx xxx process xx undo xxx xxxxxxxxxx xx isolate x. If yxx xxxx x quadratic xxxxxxxx, in xxxxx xxxxx xx an x^x and xx x, yxx will xxxx to xxxxxx xxx xxx quadratic xxxxxxx to xxxxxxxxx xxx xxxxx(x) of x or yxx xxxxx xxxx to xxxxxx the xxxxxxxx. xxx xxx purposes xx this xxxxxxx, xx xxxx consider xxxxxx equations xxxy, xx xxxxx there xx only xxx xxxxxxxx. For xxxx info xxxxx xx. xxxxxx do xxxxx https://www.khanacademy.org/math/algebra/solving-linear-equations-and-inequalities/basic-equation-practice/v/equations-3
