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 + 2c = 9c + 4x - 9 for c in terms of x.
| 1\(\frac{3}{4}\)x - \(\frac{1}{2}\) | |
| -\(\frac{2}{11}\)x + \(\frac{9}{11}\) | |
| -2\(\frac{1}{2}\)x + 4 | |
| x + \(\frac{9}{17}\) |
