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