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 -9b - 8b = -8b - 7z - 4 for b in terms of z.
| -\(\frac{5}{11}\)z - \(\frac{4}{11}\) | |
| -13z + 2 | |
| -z - \(\frac{2}{3}\) | |
| -z + 4 |
