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 - 2c = -5c - 3x + 7 for c in terms of x.
| 10x + 9 | |
| \(\frac{2}{5}\)x - \(\frac{2}{5}\) | |
| -\(\frac{1}{3}\)x + 1\(\frac{2}{3}\) | |
| -\(\frac{1}{8}\)x + \(\frac{7}{8}\) |
