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 = -4c + 3x + 2 for c in terms of x.
| 13x - 2 | |
| x - 1\(\frac{1}{2}\) | |
| 4x + 3 | |
| \(\frac{5}{13}\)x + \(\frac{2}{13}\) |
