what is the correct order pair for 3x +4y =38 5x -5y = -30
3x + 4y = 38 5x - 5y = -30
* 5 * 4
------------------ -----------------
15x + 20y = 190 20x - 20y = -120
Add them.
15x + 20y = 190
+ (20x - 20y = -120)
-----------------------------
35x = 70
x = 2
5x - 5y = -30
5(2) - 5y = -30
10 - 5y = -30
-5y = -40
y = 8
(2, 8)
