Lesly Diaz · Answer 1

Solve first to find y and - 9+9 = 0

-9x+4y=-17

9x-6y=3

2y = - 14

Y = - 14/2

Y=-7

Substitute your y answer into first equation solve to find x.

-9x+4 (-7) = - 17

-9x-28 = - 17

-9x = - 17+28

-9x = 11

X = 11/-9

X = - 1.2222 or - 1 and 2/9

So answer is (-1.2222, - 7)
