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 a - 9a = -3a - x + 9 for a in terms of x.
| -\(\frac{2}{5}\)x + 1\(\frac{4}{5}\) | |
| 2x + 2\(\frac{1}{4}\) | |
| -3x + 2\(\frac{1}{3}\) | |
| \(\frac{1}{11}\)x - \(\frac{6}{11}\) |
