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 = 2b + 3y - 4 for b in terms of y.
| -\(\frac{4}{7}\)y - \(\frac{1}{7}\) | |
| 1\(\frac{5}{7}\)y - \(\frac{4}{7}\) | |
| \(\frac{1}{2}\)y - \(\frac{5}{18}\) | |
| -1\(\frac{2}{9}\)y - 1 |
