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