vybez:

the length of a side can be found by substituting this value into either expression.

imyoursgirlsgirl:

wait i got -11 which i think is wrong

vybez:

3x = 21 x = 7

mhanifa:

You are right, I got it wrong x = 7

imyoursgirlsgirl:

oh ok

mhanifa:

Consider all sides of the same length. 5x - 27 = 2x - 6 Solve for x: 3x = 21 x = 7 Now you can find the side length by substituting x with its value. 5*7 - 27 = 35 - 27 = 8

imyoursgirlsgirl:
