What must be subtracted from 2a – 4abc to get – 8a + 6abc ?.....plz give in step by step answer...spam will be reported

Answer 1

Answer:

Let q should be subtracted.

Then, according to question,

2a+8b+10−q=−3a+7b+16

⇒−q=−3a+7b+16−(2a+8b+10)

⇒−q=−3a+7b+16−2a−8b−10

⇒−q=−3a−2a+7b−8b+16−10

⇒−q=−5a−b+6

⇒q=−(−5a+b+6)

⇒q=5a+b−6.
