Question

anonymous · Answer

9x-2y=3 and 3x-6y=y 

on the right is that really supposed to equal y?

anonymous · Answer

the problems were on top of one another and it just tells me to solve it and see if it has a solution

anonymous · Answer

ok, well then we can start with the equation on the right.

3x -6y = y

3x = 7y 

x = (7/3)y .

(7/3)y into the first equation wherever you see x.

using the set builder notation

substitute x = (7/3)y into the first equation to get: 9(7/3y)-2y=3 then solve for y.
