 Question 347855: The problem says for me to solve but I don't even know how to begin. I know I need an LCM but what is it, 3x? Then what, do I divide both sides by the 3x? WHen I did that I came up with 6 = 21 + x solve for x: 6-21=x -15=x Is this right? 2/x = 7/x - 1/3Answer by stanbon(57354)   (Show Source): You can put this solution on YOUR website!2/x = 7/x - 1/3 ---- Multiply both sides by 3x to get rid of the denominators. 6 = 21 - x x = 21-6 x = 15 ================= Cheers, Stan H.
