hi


would like to confirm on the below working, my DD complain the solution halfway

Jane have $12 more than Linda and $46 more than Tom. They have a total of $500. how much money has Jane?

3U->500+12+46
why add? I thought is minus since we are finding equal 3U

Hi,

Because,

Jane = Linda + 12 = Tom + 46

U = Jane
U = Linda + 12
U = Tom + 46

Then,

3U = Jane + Linda + Tom + 12 + 46
3U = 500 + 12 +46

hi

why not

3U = 500-46-12? I see some other type of qns, they use this method
