What is the solution to the following system of equations?
[9x - 7y = 22]
[x + 3y= -24

A. x = 4, y = 2
B. x = 3, y = -9
C. x= 0, y= -8
D. x= -3, y = -7

D) x=-3, y=-7

Step-by-step explanation:

9x - 7y = 22

x + 3y= -24

9x - 7y = 22

x= -24-3y

9(-24-3y)-7y=22

x= -24-3y

-216-27y-7y=22

x= -24-3y

-34y=22+216

x= -24-3y

-34y=238

x= -24-3y

y=238/(-34)

x=-24-3y

y=-7

x=-24-3*(-7)

y=-7

x=-24+21

y=-7

x=-3

(x,y)=(-3,-7)

1. sometimes

2. never true

3. sometimes

these are pretty self explanatory if you know what supp right and com angles are
