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 -5c - 9c = -8c - 3x - 8 for c in terms of x.
| 2x - 2\(\frac{2}{3}\) | |
| -3\(\frac{1}{3}\)x - 2\(\frac{2}{3}\) | |
| 1\(\frac{1}{5}\)x - \(\frac{1}{5}\) | |
| 3x + 1 |
