Answer:

c. 2

Explanation:

simplify:

3x-9x+7-3 = -8

-6x+4 = -8

Subtract 4 from both sides:

-6x = -8 - 4

-6x = -12

Divide both sides by -6:

x = -12/ -6

Answer

x= 2

Answer: C. 2

Explanation:

1. combine like terms

-6x + 4 = -8

2. Make x be by itself by subtracting -4 by both sides of the equal sign

-6x = -12

3. Divide both sides by -6, then negatives will cancel out

x= 2

(hope this helped)
