w in (-oo:+oo)
2*(w+17/4)+2*w = 265/2 // - 265/2
2*(w+17/4)+2*w-(265/2) = 0
2*(w+17/4)+2*w-265/2 = 0
(2^2*(w+17/4))/2+(2*2*w)/2-265/2 = 0
2^2*(w+17/4)+2*2*w-265 = 0
8*w-265+17 = 0
8*w-248 = 0
(8*w-248)/2 = 0
(8*w-248)/2 = 0 // * 2
8*w-248 = 0
8*w-248 = 0 // + 248
8*w = 248 // : 8
w = 248/8
w = 31
w = 31
