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