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 = a - 5z + 8 for a in terms of z.
| -3z + 1\(\frac{1}{4}\) | |
| \(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| 1\(\frac{2}{3}\)z + 1\(\frac{1}{6}\) | |
| -\(\frac{2}{3}\)z - \(\frac{2}{3}\) |
