Question

Which ordered pair is a solution of the equation? 5x-2y=185x−2y=18

Answer 1

Only (4,1)

Explanation:

Answer 2

The answer is x = 0 and y = -9.

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.
