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 + 9z + 5 for b in terms of z.
| 1\(\frac{1}{7}\)z + 1\(\frac{1}{7}\) | |
| -3\(\frac{1}{2}\)z - \(\frac{1}{2}\) | |
| -z - 5 | |
| -11z - 2 |
