X+15=Y ; Y=X+15
Y-12=Z ; Z=(X+15)-12 ; Z= X+3
Z x X=70 ; (X+3)xX = 70 ; X^2 +3X =70
X^2 +3X-70=0; (X+10)x(X-7)=0;
Thus solution for X are
X=-10, and X=7
As Z+Y+X=W
W= (X+3) + ( X+15) + (X) = 3X +18
With X=7, we get
W= 3*7+18 =39
With X=-10, W= 3*(-10)+18 = -12

y = x + 15
Substitute
X+15-12=Z
X+3=Z
(X+3) x X = 70
Xpower 2 +3X-70 = 0
Easy equation
3x+18=w
Get X from above

Sorry but I have already graduated and I don't do homework any more. But if I had to guess I would guess 39. Only because I cheated off the person who answered already. (ironically, that's what i did in high school too.) :-)
