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 -3a - 5a = -9a - 5z - 2 for a in terms of z.
| -\(\frac{7}{11}\)z - \(\frac{4}{11}\) | |
| -\(\frac{2}{7}\)z - \(\frac{4}{7}\) | |
| -\(\frac{5}{6}\)z + 1\(\frac{1}{2}\) | |
| z - \(\frac{1}{3}\) |
