4/20 + 2/13 = 92/260 or 23/65
1 13/20
144 + 13 + 20 = 177
20+18+13+9=60
Without an equality sign the given expression is not an equation but it can be simplified to: W-15
4/20 + 2/13 = 92/260 or 23/65
The sum of 4/20 and 2/13 is 23/65
1 13/20
4/20 + 2/13 = 26/130 + 20/130 = 46/130 = 23/65
144 + 13 + 20 = 177
7x=20+20x collect terms containg x on one side and then factorize -13x=20 0r, x=-20/13
20+18+13+9=60
Without an equality sign the given expression is not an equation but it can be simplified to: W-15
-20 + 13 = -7
First, subtract 20 and 5. Then take that answer and subtract 13 from it. 20-5-13 15-13 2 The answer is 2
(20 - x)/5
13/20 - 3/5 = 13/20 - 12/20 = 1/20
