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 -b - 7b = -2b - 6z - 6 for b in terms of z.
| \(\frac{1}{8}\)z - \(\frac{3}{4}\) | |
| z - 6 | |
| \(\frac{1}{3}\)z + \(\frac{2}{5}\) | |
| -2\(\frac{1}{5}\)z + \(\frac{4}{5}\) |
