If the measure of angle 1 = 36 degrees and the measure of angle 2 = x + 3, what is the measure of angle 3?
36 + x + 3 + x + 180
39 + 2x = 180
39-39 + 2x = 180 +39
2x =219
x = 109.5
36 + x + 3 + x + 180
39 + 2x = 180
39-39 + 2x = 180 +39
2x =219
x = 109.5

If the problem says that one angle of a triangle is three more than the other, then
36 + x + x+3 = 180
2x = 141
x = 70.5
You subtracted 39 on the left, but added 39 on the right.
36 + x + x+3 = 180
2x = 141
