-20+20w=73
You need to get your variable by itself. Try to section your problem off if you need to. I always like to do my order of operations backwards. The inverse operation of -20 is adding 20 so to cancel that out you need to add 20 to each side. Now you are left with 20w=93.Now you need to get rid of the 20. The inverse of multiplying is dividing. So divide both sides by 20. You are left with 1w=4.65. Which is the same w=4.65 or you could say w=4 13/20. Hope this helps.
