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 - 3a = -a + 5x - 8 for a in terms of x.
| 4\(\frac{1}{2}\)x - 1 | |
| x - \(\frac{3}{14}\) | |
| -\(\frac{6}{7}\)x + \(\frac{2}{7}\) | |
| 4x - 4 |
