By process of elimination. 3y and -3y get eliminated. Giving you
3x=18
Divide by 3 on each side
Giving you x=6
Plugging it into equation 2 you get
(6)-3y=3
Taking out the parenthesis you have
6-3y=3
Subtract by 6 on each side giving you
-3y=-3
Divide by -3 on each side giving you
y=1
So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)
2.5 should be correct unless im doing the problem wrong
