{x=2+y
{-6x-6y=-12
-6(2+y) -6y = -12
-12 - 6y - 6y = -12
-12y = -12 + 12
-12y = 0
y = 0
x = 2 + y = 2 + 0 = 2
Answer: x=2, y=0
Answer:

We solve the problem like this:
Since 3 is proportional to 6 and 9 is proportional to x, we set up a proportion.
3/9 = 6/x
We then use cross-multiplication to solve for x.
