the answer to your question is c
(x - 3) + (x - 6) + x = 63
x - 3 + x - 6 + x = 63
Combine like terms
3x - 9 = 63
Isolate the constant
3x - 9 + 9 = 63 + 9
3x = 72
Isolate the viable
3x / 3 = 72 / 3
x = 24
Answer:

Step-by-step explanation:
1. Subtract 8x from both sides:
8x-6y-8x=36-8x
2. Simplify:
-6y=36-8x
3. Divide both sides by -6

4. Simplify to get answer
Answer: (8)(-4.5)
Step-by-step explanation: If you were to multiply -4.5 • -8 it would be a positive number but if you multiply (8)(-4.5) that would equal a negative number
