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 3b - 4b = 7b - 9z + 1 for b in terms of z.
| 1\(\frac{1}{4}\)z - \(\frac{1}{4}\) | |
| z - \(\frac{1}{14}\) | |
| 2\(\frac{1}{2}\)z - 1\(\frac{3}{4}\) | |
| -\(\frac{1}{2}\)z + \(\frac{1}{6}\) |
