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 -3c + 4c = -c + x + 9 for c in terms of x.
| -\(\frac{1}{2}\)x + \(\frac{2}{5}\) | |
| -\(\frac{7}{8}\)x - \(\frac{1}{8}\) | |
| -\(\frac{7}{9}\)x + 1 | |
| 1\(\frac{1}{2}\)x - 4\(\frac{1}{2}\) |
