Question 191071
1).Given the following equation, 4x – 2y = 12; solve for y. 
4x – 2y = 12
2x - y = 6
-y = 6-2x
y = 2x - 6
-------------------
2).Verify that the ordered pair (3, -3) is a solution to the equation 
3x + 4y = -3
Sub 3 for x and -3 for y.
3*3 + 4*(-3) =? -3
9 - 12 = -3
So it is a solution.
