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 7c - 2c = -7c - 3x + 9 for c in terms of x.
| -\(\frac{1}{14}\)x + \(\frac{9}{14}\) | |
| 4\(\frac{1}{4}\)x - \(\frac{1}{4}\) | |
| -2\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| -1\(\frac{3}{8}\)x - \(\frac{1}{2}\) |
