Question

y = -2x + 9

5x - 2y = 18

Answer 1

(0,-9)

Step-by-step explanation:

y=-2x+9

5x-2y=18

so then

5x-2y=18

-2x-y=9

how get rid of the y by multiplying the second equation by -2

5x=18

4x=-18

now add

9x=0

x=0

now for y you substitute the x in for one of the equations

5x-2y=18

-2x=18

x=-9
