3/20 + 1/10 is the same as 3/20 + 2/20 which equals 5/20 which turns out to be 1/4 or 0.25 in decimal
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5

1 over 3 plus 1 over 12 equals 5 over 12
7/20 + 3/9 = 41/60
20 = 400
3/20 + 1/10 is the same as 3/20 + 2/20 which equals 5/20 which turns out to be 1/4 or 0.25 in decimal
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5

x+3 = 20 x = 20-3 x = 17
58
1 over 3 plus 1 over 12 equals 5 over 12
if 'g' = minus 3 then 20 + -3 = 17 17 + -3 = 14
-3
i suppose 20 as an answer if its not a trick question.
x=3
