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 7c - 8c = -5c - 3x - 6 for c in terms of x.
| 3x + 8 | |
| \(\frac{5}{12}\)x - \(\frac{1}{2}\) | |
| \(\frac{1}{7}\)x - \(\frac{5}{7}\) | |
| -2\(\frac{1}{4}\)x - \(\frac{1}{4}\) |
