Answer:
C = 8
Step-by-step explanation:
So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:
C - 12 = -4
C - 12 + 12 = -4 + 12
C = 8
It a because negative times a negative is a positive
Answer:
x = -11
Step-by-step explanation:
3x - 4 + 2(x - 5) = 9x + 8 - 2x
3x - 4 + 2x - 10 = 9x + 8 - 2x
3x + 2x - 9x + 2x = 8 + 10 + 4
- 2x = 22
- x = 22/2
- x = 11
x = - 11
