2(w+18+W)=2(w+18−6+w+3)
perimeter is 126
my teacher ask to get the value of W

math  eh? 
Steve,
assuming that W is the same as w, we have
2(w+18+W)=2(w+18−6+w+3)
2w+36+2w = 2w+3612+2w+6
0 = 6

No value of w makes the equation true
Since you're talking perimeter, shouldn't there be a length or something involved?
I think the problem is garbled.
