Well, darling, 17 over 18 minus 2 over 3 is the same as 17 times 3 minus 2 times 18, all over 18 times 3. So, that gives you 51 minus 36 over 54, which simplifies to 15 over 54, or 5 over 18. Math doesn't have to be a drag, honey!
2 over 3 = 18 over x+5... x=22 because (x+5) needs to equal 27 for the equation to be true.
27 times 5 is 135.
5 goes into 27 5 times because 5 times 5 is 25 and it is the closest you can get to 27 when dividing by 5.
