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 -4a - 6a = 5a + 3z + 2 for a in terms of z.
| -\(\frac{1}{3}\)z - 2 | |
| -z - \(\frac{2}{9}\) | |
| -\(\frac{1}{3}\)z - 3 | |
| 13z + 2 |
