Answer 1

$\huge{♡}\underline{\mathtt{\red{A}{\pink{N}{\blue{S}{\green{W}{\purple{E}{\orange{R}}}}}}}}\:{♡}$

$(4a + 16b ) - (2a + 9b) \\ = (4a - 2a) + (16b - 9b) \\ = 2a + 7b(Ans.)$

Answer 2

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.
