When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -4c - 4c = 6c - 8x - 4 for c in terms of x.
| -3x - 6 | |
| 3x + 1 | |
| -3x + 4\(\frac{1}{2}\) | |
| \(\frac{2}{5}\)x + \(\frac{2}{5}\) |
