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 7b + 9b = b + z - 6 for b in terms of z.
| 2\(\frac{2}{3}\)z + 2\(\frac{2}{3}\) | |
| -\(\frac{2}{7}\)z - \(\frac{1}{14}\) | |
| -1\(\frac{1}{3}\)z - 1 | |
| -z - \(\frac{1}{10}\) |
