B. Y/4=12
C. 2(4y)=12
D. Y+4=12

notice that they used the *subtraction property of equality*. when you're solving equations and isolating a variable, you perform the opposite operation to the one being performed on the variable. in other words, since they used *subtraction* you should be looking for *the opposite of subtraction* being applied to the variable in the equation.
