Mathematics
1 answer:
erma4kov [3.2K]3 years ago
6 0

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)
