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 -6c + 9c = 6c - 5x - 9 for c in terms of x.
| -3\(\frac{1}{2}\)x - 4\(\frac{1}{2}\) | |
| \(\frac{1}{18}\)x + \(\frac{2}{9}\) | |
| 1\(\frac{1}{6}\)x + \(\frac{3}{4}\) | |
| -1\(\frac{4}{5}\)x + \(\frac{2}{5}\) |
