So we are given that the perimeter is 106 and two problems to solve we will write this as an equation 106 = 3x + 6 we will subtract 6 from both sides 100 = 3x now divide by 3 to isolate the variable we will get 33 1/3 as the x
for the second one 106 = 2x - 3 add three to both sides 109 = 2x divide by 2 to isolate the variable we will get 54 1/2 as the x
