What is the awnser to -9xt4y=-17 9x-6y=3

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)
