Question 26639
There are several ways to solve this problem.  Let's use the substitution method.  Since we know the value of x (x=3y), we can substitute this value in the second equation and solve for y. 


3y-6=2x
3y-6=2(3y)
3y-6=6y
-6=-3y+6y
-6=3y
-6/3=y
-2=y


Now that we have the value for y we can go back and substitute this in either equation and solve for x.
x=3y
x=3(-2)
x=-6


So, x=-6 and y=-2.
