3-30.

For the following equations, draw a picture of the tiles in an equation mat, use “legal” moves to simplify, and solve for the variable. Record your work.

1. $−3x+7=−x−1$

For more help solving this problem, see problem 2-105.

$x=4$

1. $1−2p+5=4p+6$

For part (b), assume that $p=x$.

Use the eTools below to move the tiles for each equation.
