Solution
Let q 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
Let q 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
