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 + 4a = a - 8z + 2 for a in terms of z.
| 1\(\frac{1}{16}\)z + \(\frac{1}{8}\) | |
| -\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| z - \(\frac{1}{2}\) | |
| 1\(\frac{1}{3}\)z - \(\frac{2}{9}\) |
