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 - 8a = -2a - 9z + 3 for a in terms of z.
| \(\frac{4}{5}\)z + 1\(\frac{1}{5}\) | |
| -3\(\frac{1}{3}\)z - 2\(\frac{2}{3}\) | |
| -\(\frac{1}{6}\)z + \(\frac{1}{2}\) | |
| -\(\frac{2}{3}\)z + \(\frac{1}{3}\) |
