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 5a - a = -a - 2x - 8 for a in terms of x.
| 2x - 6 | |
| -\(\frac{1}{6}\)x - 1\(\frac{1}{3}\) | |
| -1\(\frac{1}{11}\)x - \(\frac{4}{11}\) | |
| -1\(\frac{2}{7}\)x - \(\frac{3}{7}\) |
