Take away : `2/3+a c-5/7a b+2/3b c\ from3/2a b-7/4a c-5/6b c`

Text Solution

Verified by Experts

` 2/3ac – 5/7ab + 2/3bc` from `3/2ab -7/4ac – 5/6bc`
`3/2ab – 7/4ac – 5/6bc – (2/3ac – 5/7ab + 2/3bc)`
`3/2ab + 5/7ab – 7/4ac – 2/3ac – 5/6bc – 2/3bc`
`(21ab+10ab)/14 – (21ac-8ac)/12 – (5bc-4bc)/6`
`31/14ab-29/12ac-3/2bc`
