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 + 8a = -4a + 7x - 9 for a in terms of x.
| -\(\frac{1}{3}\)x - 2 | |
| -\(\frac{1}{12}\)x - \(\frac{3}{4}\) | |
| -\(\frac{1}{8}\)x + \(\frac{1}{4}\) | |
| -\(\frac{1}{2}\)x - \(\frac{1}{3}\) |
