Answer by Pieter(35) About Me  (Show Source):
You can put this solution on YOUR website!
2x + 2y = 25 and you know that y = 3
you simply put this 3 in the equation where y stands:
2x + 2*3 = 25
now bring everything that is not x to the other side:
2x = 25 - 6 = 19
so x = 19/2 = 9.5
is this what you meant?
