@ptvrazz 

for x-4y=6

you divide negative -4y by positive 4 and 6  divided by positive 4

which cancels out the -4 and leaves you with y and on the other side you have 6 divided by 4 which is 1.5

see where i am going with this?

and then 1.5 will be your x

but hold on i dont see that in the choices so i must be doing something wrong here
