Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation. A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. Whatever we do to one side, has to be done on the opposite side. 

8x - 4y = -12 

4(2x-y)=-12

 
   Factor \ out \ the \ common \ term \ 4

2x-y=- \dfrac{12}{4}    Divide \ both \ sides \ by \ 4

2x-y=-3

 

 

-y=-3-2x       Subtract \ 2x \ from \ both \ sides

y=3+2x        Multiply \ both \ sides \ by \ -1

Is this right? I’m confused for answering either B or C.
boyakko [2]

your profile says you're 22 but I find that painfully challenging to believe. She knits 5 scarves in 2 hours. Divide 10 by 2, you get 5. 5x5 is 25. It's C. You shouldn't need help. This is sad.
