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 9c - c = -3c - 9x + 1 for c in terms of x.
| -\(\frac{2}{3}\)x + \(\frac{1}{12}\) | |
| 3x - \(\frac{4}{5}\) | |
| -x - 1 | |
| -3x + 2\(\frac{2}{3}\) |
