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 -a + 3a = -4a - 8z - 8 for a in terms of z.
| \(\frac{5}{12}\)z - \(\frac{7}{12}\) | |
| -3\(\frac{2}{3}\)z - 2\(\frac{2}{3}\) | |
| \(\frac{2}{9}\)z - 1 | |
| -\(\frac{4}{9}\)z - \(\frac{2}{9}\) |
