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