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 - 6b = 7b - 4y - 9 for b in terms of y.
| y + 7 | |
| -\(\frac{2}{5}\)y + 1\(\frac{4}{5}\) | |
| 2y - 2\(\frac{1}{2}\) | |
| \(\frac{11}{12}\)y - \(\frac{7}{12}\) |
