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 3a - 5a = -4a + 9x - 9 for a in terms of x.
| \(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| \(\frac{1}{2}\)x + \(\frac{5}{12}\) | |
| 2x - 1\(\frac{2}{7}\) | |
| 2\(\frac{1}{6}\)x - \(\frac{2}{3}\) |
