i think u wrote it incorrectly did u mean x+y= 9?? if so
x +y= 9
2x-y=-3
3x = 6
x = 2
or
x +y= 9 (-2) -2x-2y=-18
2x-y=-3 2x- y=-3
-3y=-21
y=7
u can use the elimination process to solve for both or u can solve for one and plug it in any one of the equations to solve for the other
x +y= 9
2x-y=-3
3x = 6
x = 2
or
x +y= 9 (-2) -2x-2y=-18
2x-y=-3 2x- y=-3
-3y=-21
