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 -9c + 2c = 8c + 3x - 4 for c in terms of x.
| -\(\frac{1}{10}\)x + \(\frac{9}{10}\) | |
| -\(\frac{1}{17}\)x + \(\frac{4}{17}\) | |
| x - 1\(\frac{1}{7}\) | |
| 5x - 3 |
