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