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 - 4a = 3a + 5z - 6 for a in terms of z.
| -1\(\frac{1}{6}\)z - \(\frac{1}{6}\) | |
| \(\frac{1}{4}\)z - 1 | |
| 9z - 6 | |
| 1\(\frac{1}{8}\)z - \(\frac{3}{8}\) |
