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 -6b + 5b = -8b - 8z + 9 for b in terms of z.
| -6\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) | |
| 1\(\frac{1}{12}\)z - \(\frac{1}{6}\) | |
| z + \(\frac{3}{14}\) | |
| -5z - 3 |
