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 - 5b = -6b - 5y - 7 for b in terms of y.
| 9y - 4 | |
| y + 1\(\frac{1}{2}\) | |
| y + 2\(\frac{1}{3}\) | |
| -y + 1 |
