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 + 9b = 3b + 9z + 4 for b in terms of z.
| z + \(\frac{2}{3}\) | |
| -\(\frac{1}{2}\)z - 1\(\frac{3}{4}\) | |
| -\(\frac{1}{4}\)z + \(\frac{3}{8}\) | |
| -\(\frac{5}{14}\)z - \(\frac{1}{2}\) |
