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 - 9c = c - 6x + 6 for c in terms of x.
| -1\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| 2\(\frac{1}{2}\)x - 1\(\frac{1}{4}\) | |
| -6\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) | |
| -\(\frac{3}{10}\)x - \(\frac{3}{5}\) |
