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 2b - 4b = -7b + 7z - 2 for b in terms of z.
| 1\(\frac{2}{9}\)z - \(\frac{2}{9}\) | |
| -z - \(\frac{1}{5}\) | |
| -2z - 3 | |
| \(\frac{1}{14}\)z - \(\frac{2}{7}\) |
