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 -9a + a = a - 6x + 3 for a in terms of x.
| 4\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| \(\frac{7}{8}\)x + \(\frac{1}{4}\) | |
| \(\frac{7}{10}\)x - \(\frac{3}{10}\) | |
| -13x + 1 |
