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 2b - b = -7b + 9z + 6 for b in terms of z.
| \(\frac{1}{2}\)z + \(\frac{3}{5}\) | |
| 1\(\frac{1}{9}\)z + \(\frac{2}{3}\) | |
| -2\(\frac{3}{7}\)z + \(\frac{4}{7}\) | |
| \(\frac{3}{8}\)z - \(\frac{1}{8}\) |
