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 - 2a = 3a - 4z - 6 for a in terms of z.
| z - \(\frac{1}{2}\) | |
| \(\frac{1}{2}\)z + \(\frac{5}{18}\) | |
| -\(\frac{2}{5}\)z - 1\(\frac{1}{5}\) | |
| 7z + 4 |
