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 -8c + 5c = -9c - 7x - 8 for c in terms of x.
| -12x - 8 | |
| -2\(\frac{1}{7}\)x - 1\(\frac{2}{7}\) | |
| 2\(\frac{4}{5}\)x + 1\(\frac{2}{5}\) | |
| -2\(\frac{1}{6}\)x + \(\frac{5}{6}\) |
