Answer:
The answer is x = 0 and y = -9.
Step-by-step explanation:
Here we have two equations:
5x-2y=18
185x−2y=18
we do the subtraction by each side like
(185x - 2y ) - (5x- 2y) = 18 - 18
so we find: 185x - 2y -5x +2y =0
or 180x =0, and x=0
Replace x=0 into: 5x - 2y = 18
we have: 5*0 - 2y =18
or -2y =18
and y = 18/(-2)
y = -9
The answer is x = 0 and y = -9.
