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 + 2a = -9a + 8x - 2 for a in terms of x.
| 2x - 6 | |
| x - \(\frac{1}{3}\) | |
| -\(\frac{2}{3}\)x - \(\frac{5}{6}\) | |
| x - \(\frac{1}{18}\) |
