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 - 8b = -8b - 9z - 5 for b in terms of z.
| -\(\frac{1}{7}\)z - \(\frac{5}{7}\) | |
| z - \(\frac{5}{13}\) | |
| z + 1\(\frac{1}{5}\) | |
| z + \(\frac{2}{5}\) |
