Question

What should be subtracted from 2ab + 8b -10 to get – 7ab – 11ab + 24?​

Answer 1

Step-by-step explanation:

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.

Answer 2

Answer:

something should be subtracted from 2ab +8b-10 to get -7ab-11ab+24 .

let that something be X .

so

2ab+8b-10 -X= -18ab+24

now on solving ,

X = 20ab+8b-34 ==> this is your answer
