For the following equations, draw a picture of the tiles on an Equation Mat. Then use “legal” moves to simplify and solve for the variable. a. -2+x = -x+2

b. 2+3x = x+7

I can solve these for you

a:
-2+x=-x+2
+2 +2
x=-x+4
+x +x
2x=4
— —
2 2
x=2

so the solution to a is x=2

b:
2+3x=x+7
-2 -2
3x=x+5
-x -x
2x=5
__ __
2 2
x=2.5, or 2 1/2

so the solution to b is x= 2 1/2
