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 4b - 4b = 5b - 2y + 4 for b in terms of y.
| -2y - 4 | |
| -17y + 1 | |
| -\(\frac{1}{2}\)y - 2 | |
| 3y - 3 |
