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 + 8c = -9c - 6x + 4 for c in terms of x.
| 6x - 1 | |
| 1\(\frac{4}{5}\)x - \(\frac{2}{5}\) | |
| -2\(\frac{4}{5}\)x + \(\frac{4}{5}\) | |
| 3x - 4 |
