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 = -3a + 7z + 6 for a in terms of z.
| 3\(\frac{1}{4}\)z - \(\frac{1}{4}\) | |
| 3\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| -\(\frac{1}{12}\)z + \(\frac{1}{2}\) | |
| -z + 4 |
