15w - 15 = 180
15w = 195
w =195 / 15
w = 39 / 3
w = 13

(4w - 28) + (11w + 13) = 180
4w - 28 + 11w + 13 = 180
15w - 15 = 180 + 15
15w = 195
w = 195 / 15 or 39/3 or 13
Answer: w = 13
Proof:
(4[13] - 28) + (11[13] + 13) = 180
(52 - 28) + (143 + 13) = 180
24 + 156 = 180
180 = 180

4w-28+11w+13 = 180
15w = 180-13+28
15w=195
w=13

(4w-28)+(11w+13)=180
4w-28+11w+13=180
15w-15=180
15w=180+15
15w=195
w=195/15
w=13 Ans.

The brackets are useless, so forget about them :P
15w - 15 = 180
15w = 195
w = 13
