The length of a rectangle is 2 less than 3 times the width . the perimeter is 60 inches . find the widtha.8 inchesb.22 inchesc.15.5 inchesd.20.7 inches

If the length is 3x the width -2 then you would count the width 8 times, 2 for the width and 3 for each length and -4, -2 for each length.This makes the equation 8w-4=60 if w is width.
8w-4=60
8w-4+4=60+4
8w=64
8w/8=64/8
w=8
Your answer is A: 8 inches
