$2x + 3y + x - y + 4$
$\bigcirc$ $3x + 4y + 4$
$\bigcirc$ $3x + 2y$
$\bigcirc$ $9xy$
$\bigcirc$ $3x + 2y + 4$

Explanation:

Step1: Group like x terms

$2x + x + 3y - y + 4$

Step2: Combine x terms

$(2+1)x + 3y - y + 4 = 3x + 3y - y + 4$

Step3: Combine y terms

$3x + (3-1)y + 4 = 3x + 2y + 4$

Answer:

D. $3x + 2y + 4$
