• 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 $3x+7y$, $6x-2y$

$3x+2y$ + $2x+7y$ =$5x+9y$ $\ne 9x+5y$
$4x+4y$ + $5x+y$ =$9x+5y$ $=9x+5y$
$3x+7y$ + $6x-2y$ =$9x+5y$ $=9x+5y$
$3x+3y$ + $4x+7y$ =$7x+10y$ $\ne 9x+5y$
