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 = -b + 6z + 8 for b in terms of z.
| -1\(\frac{1}{6}\)z + \(\frac{1}{6}\) | |
| 15z + 8 | |
| -5\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) | |
| -5z - 2\(\frac{1}{3}\) |
