-x-8y=-18
x +9y=21
A) (-6,3) B) (6, -3)
c) (6,9)
D) (6,3)
1 answer:
Answer:
A) (-6,3)
Step-by-step explanation:
-x-8y=-18
x +9y=21
Add the two equations together to eliminate x
-x-8y=-18
x +9y=21
-------------------
y = 3
Now we need to find x
x +9y = 21
Substitute in y
x +9(3) =21
x+27 = 21
Subtract 27 from each side
x+27-27 = 21-27
x = -6
