Homework Help: Grade 10-Math

Posted by peyton on Saturday, September 24, 2011 at 5:19pm.

x+2y=3
5x+4y=8

I isolated x+2y=3 to make: x=3-2y
then i began to sub in equation one with equation two:
5x+4y(3-2y)=8
5x+12-8y=8

after that i began to try to solve the equation but my answers were not correct. any help would be greatly appreciated!
