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 -2a - a = -8a - 3z - 6 for a in terms of z.
| -\(\frac{3}{8}\)z + 1 | |
| -\(\frac{1}{3}\)z - 1 | |
| z - \(\frac{1}{5}\) | |
| z - \(\frac{7}{11}\) |
