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 = -2a + 6z + 6 for a in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{1}{8}\) | |
| \(\frac{6}{13}\)z + \(\frac{2}{13}\) | |
| \(\frac{5}{9}\)z - \(\frac{1}{9}\) | |
| -1\(\frac{1}{3}\)z - 1 |
