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