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