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 = 9a - 7z - 5 for a in terms of z.
| -1\(\frac{1}{2}\)z - \(\frac{3}{8}\) | |
| 3z - 4\(\frac{1}{2}\) | |
| 15z + 5 | |
| 5\(\frac{1}{2}\)z - 4 |
