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

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.
