X=12/3
x=4

Answer 2

does that make sense to you ?

not really

Answer 4

Well when u look at your equation there are two variables X and Y , we need to have one variable to solve the equation. So they have given you to get rid of the Y variable. I just replaced the Y variable with what the equation told me Y was equal to. so then I had only one variable to deal with. X :)
