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 -2c + c = c + 3x - 9 for c in terms of x.
| 2\(\frac{2}{3}\)x + \(\frac{1}{3}\) | |
| \(\frac{1}{10}\)x - \(\frac{3}{10}\) | |
| -4x - 4 | |
| -\(\frac{2}{3}\)x + 3 |
