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