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 7b - 6b = 3b + 4z - 1 for b in terms of z.
| -\(\frac{2}{3}\)z + 2\(\frac{2}{3}\) | |
| 1\(\frac{1}{8}\)z - \(\frac{1}{8}\) | |
| \(\frac{9}{14}\)z + \(\frac{1}{7}\) | |
| 2\(\frac{1}{2}\)z - \(\frac{1}{4}\) |
