Question 1065848: X=2y-2
3y=x+6
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! x=2y-2
3y=x+6 subtract 3y and x from both sides
-x = -3y+6 now add this equation to the first one above:
x = 2y-2
+
-x = -3y+6
----------
0x = -y+4 add y to both sides:
y = 4 now find x:
x = 2y-2
x = 2(4)-2
x = 6
Now let's try these answers on the second equation:
3y = x+6
3(4) = 6+6
12 = 12 Correct.
