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 c - 3c = -2c - 9x + 9 for c in terms of x.
| -2x + 3 | |
| -\(\frac{1}{2}\)x - \(\frac{1}{8}\) | |
| -3x + 6 | |
| \(\frac{3}{11}\)x + \(\frac{1}{11}\) |
