Edward solved the equation 4x + 1 = 5x + (−5) using these steps.

1. add 4 negative x-tiles to both sides.

2. add 5 negative unit tiles to both sides.

3. solution x = −4.

what was edward’s mistake?
in step 1, he had to add 4 positive x-tiles.
in step 2, he had to add 5 positive unit tiles.
in step 3, the solution should be x = 4.
edward did not make a mistake.

In step 2, he had to add 5 positive unit tiles.

Step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
