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 8c - 2c = -6c - x + 9 for c in terms of x.
| x - \(\frac{1}{12}\) | |
| \(\frac{1}{14}\)x + \(\frac{9}{14}\) | |
| 2x + 1\(\frac{2}{5}\) | |
| 3\(\frac{1}{5}\)x + \(\frac{2}{5}\) |
