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 - 2b = 6b + 9z + 5 for b in terms of z.
| \(\frac{5}{14}\)z + \(\frac{5}{14}\) | |
| -5\(\frac{1}{2}\)z - 2\(\frac{1}{2}\) | |
| 5z - 2\(\frac{2}{3}\) | |
| -\(\frac{1}{5}\)z + 1\(\frac{2}{5}\) |
