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 - 9a = -9a + 3z - 2 for a in terms of z.
| 12z - 2 | |
| z - 5 | |
| \(\frac{5}{11}\)z + \(\frac{2}{11}\) | |
| z + 3\(\frac{1}{2}\) |
