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 + 2b = -8b - 9z - 9 for b in terms of z.
| -1\(\frac{4}{7}\)z - 1\(\frac{2}{7}\) | |
| 2z + 1\(\frac{4}{5}\) | |
| -1\(\frac{4}{7}\)z - \(\frac{5}{7}\) | |
| -8\(\frac{1}{2}\)z - 4 |
