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 + 8c = 8c + 5x - 9 for c in terms of x.
| 1\(\frac{1}{2}\)x + \(\frac{1}{4}\) | |
| -\(\frac{2}{17}\)x + \(\frac{6}{17}\) | |
| 2x - 7 | |
| \(\frac{3}{17}\)x + \(\frac{9}{17}\) |
