Question

What is the value of C?
14 = -2C - 6 – 3C
​

Answer 1

-4 =C

Explanation:

14 = -2C - 6 – 3C

Combine like terms

14 = -5C - 6

Add 6 to each side

14+6 = -5C -6+6

20 = -5C

Divide each side by -5

20/-5 = -5C/-5

-4 =C

Answer 2

C = -4

Explanation:

First, combine like terms (terms with the same amount of variables):

14 = -2C - 3C - 6

14 = (-2C - 3C) - 6

14 = (-5C) - 6

Isolate the variable, C. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and equals:

Parenthesis

Exponents & Roots

Multiplication

Division

Addition

Subtraction.

First, add 6 to both sides:

14 (+6) = -5C - 6 (+6)

14 + 6 = -5C

-5C = 20

Next, divide -5 from both sides:

(-5C)/-5 = (20)/-5

C = 20/-5

C = -4

-4 is your value for C.
