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 9a - 8a = 8a + 6x - 9 for a in terms of x.
| 14x - 9 | |
| \(\frac{1}{6}\)x + \(\frac{1}{2}\) | |
| \(\frac{1}{2}\)x - 1 | |
| \(\frac{1}{3}\)x - \(\frac{5}{12}\) |
