8x - y = -9
4x - 3y = -22

Answer 1

A. 4(-8x - 9) - 3y = -22
B. 4x - 3(-8x - 9) = -22
C. 4(8x + 9) - 3y = -22
D. 4x - 3(8x + 9) = -22

Answer 2

D

Answer 3

are you sure Rod?

Answer 4

I EXPLAIN IT

Answer 5

ALRIGHT

Answer 6

8x - y = -9
-8x -8x
-y=-8x-9 -1 <-y=-8x-9 (-8x-9) -1
-1 -1

y=8x+9

Answer 7

4x-3(8x+9)=-22
so did u understand it becca
