Answer 2

Already answered

So um when this happens you will divided what number is by x or y or whatever it is to 15 and 3 in this case after that you have x+2=5

And now we invert this so the + becomes a - meaning after you do x-2 which we wont know we WILL know from 2-5 which is 3

there fore x=3
