X=12 because a half of 12 is six.

so hmm the idea behind the elimination, is to make the value atop or below, of either variable, the same but with a negative sign
so hmmm say... we'll eliminate "y"
so... let's see, we have 2y and 5y, both positive
what do we multiply 2y to get a negative -5y, that way, -5y +5y = 0 and poof it goes
well let's see, let's try "k"     

so.. if we multiply 2y by -5/2, we'll end up with -5y
well, let's multiply that first equation then by -5/2

so.. now we know x = 1.... so let's plug that in  say hmmm 2nd equation
