Answer:

The correct answer is C=3.

Explanation:

To solve this problem, we should first eliminate the parentheses on the left side of the equation. To do this, we must recognize that there is subtraction of a negative number, which is the same as adding a positive number. This gives us:

C + 8 = 5 + 2C

Next, we should move all of the variable C's to one side of the equation and move all of the constants (the number terms) to the other side. To do this, we should subtract C from both sides of the equation (to cancel out the C on the left side, moving them to the right) and subtract 5 from both sides (to cancel out the 5 on the right side and move all of the constant terms to the left).

C - C + 8 - 5 = 5 - 5 + 2C - C

If we recognize which terms cancel, we get:

8 - 5 = 2C - C

When we combine like terms through subtraction on both sides, we get:

3 = C

Therefore, the answer is that C = 3.

Hope this helps!

Answer:

C=3

Explanation:

C-(-8) = 5 + 2C

C+8 = 5+2C

Subtract C from each side

C-C+8 = 5+2C-C

8 = 5+C

Subtract 5 from each side

8-5 = 5-5+C

3 =C
