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 6a + 8a = -8a + z + 9 for a in terms of z.
| 1\(\frac{1}{6}\)z + 1 | |
| \(\frac{4}{7}\)z - \(\frac{1}{7}\) | |
| 11z - 5 | |
| -\(\frac{1}{2}\)z + \(\frac{9}{14}\) |
