Can someone please explain to me the steps taken in the proof provided to solve the linear equation? : http://i.imgur.com/2N52occ.jpg "Proof"
What I don't understand is how he removed the denominator of both fractions (3,5 respectively). I know that 3 * 5 is 15, so he just multiplied everything by 15?
Now I understand that he found the least common multiples of 3 and 5 (which I kinda already knew he was trying to do), however, did he use the 5 from the 2nd part of the equation (2m / 5) or from the first part (5/1). I think that is where I lost track.
