Question

If 2W=3X and W+Z=X+Y then what is the value of Y?

Answer 1

u have
(1) W+Z=X+Y and
(2) 2W=3X.
if u multiply (1) by 2 u get
2W+2Z=2X+2Y
and replacing (2) into this u get
3X+2Z=2X+2Y
X+2Z=2Y
Y=1/2(X+2Z)=1/2X+Z

Answer 2

I forgot to mention that Y must be in terms of W...

Answer 3

so multiply (1) by 3 and get
3W+3Z=3X+3Y
and replacing (2) into this
3W+3Z=2W+3Y
W+3Z=3Y
Y=1/3(W+3Z)=1/3W+Z
