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 4b - b = -3b + 3z + 9 for b in terms of z.
| z - \(\frac{5}{8}\) | |
| -1\(\frac{1}{6}\)z + \(\frac{1}{6}\) | |
| \(\frac{4}{7}\)z + 1\(\frac{2}{7}\) | |
| -\(\frac{10}{13}\)z - \(\frac{6}{13}\) |
