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