The length of each side of a square is
increased by 6 inches, so the perimeter
is now 36 inches. Write and solve an
equation to find the original length of
each side of the square.

Equation: 4x + 24 = 36

solution: x = 3

Step-by-step explanation:

let x be the length of the square’s side

this statement “The length of each side of a square is increased by 6 inches, so the perimeter is now 36 inches” means 4×(x + 6) = 36

4×(x + 6) = 36 ⇔ 4x + 24 = 36

                      ⇔ 4x = 12

                      ⇔ x = 3
