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 -4b - b = -5b + 8z + 5 for b in terms of z.
| -2z + 1 | |
| 9z + 5 | |
| 1\(\frac{2}{9}\)z - \(\frac{7}{9}\) | |
| -6z + 1 |
