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 -8a + 3a = -9a + 2x + 8 for a in terms of x.
| -x + 8 | |
| 1\(\frac{1}{4}\)x - \(\frac{3}{4}\) | |
| 6x + 5 | |
| x - \(\frac{1}{6}\) |
