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 - 8c = -3c + 5x + 9 for c in terms of x.
| 2x - 4 | |
| -2\(\frac{3}{5}\)x - 1\(\frac{4}{5}\) | |
| -1\(\frac{1}{2}\)x + 1 | |
| 2\(\frac{3}{5}\)x + \(\frac{2}{5}\) |
