Question

Which of the pairs given in options will add up to give $9x+5y$?

• A. $3x+2y$, $2x+7y$
• B. $4x+4y$, $5x+1y$
• C. $3x+7y$, $6x-2y$
• D. $3x+3y$, $4x+7y$

Answer 1

Answer: (B), (C)

The correct options are
B

$4x+4y$, $5x+1y$

C

$3x+7y$, $6x-2y$

$(3x+2y)+(2x+7y)=5x+9y$. So, A is not the correct option.

$(4x+4y)+(5x+7y)=9x+5y$. So, B is correct.

$(3x+7y)+(6x-2y)=9x+5y$. So, C is correct.

$(3x+3y)+(4x+7y)=7x+10y$. So, D is not the correct option.
