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