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 -2b + 9b = -b + 3z - 8 for b in terms of z.
| -\(\frac{1}{5}\)z - \(\frac{2}{5}\) | |
| 6z + 8 | |
| -13z - 4 | |
| 14z + 2 |
