is the answer

Solution :

#1 = Reorder and gather like terms.

• 4x + 3x + y + c - 3x - 3y + 2xy → (4x + 3x - 3x) + (y - 3y) + c + 2xy

#2 = Collect the coefficients of like terms.

• (4x + 3x - 3x) + (y - 3y) + c + 2xy → ( 4 + 3 - 3 ) × 6 + ( 1 - 3 ) × y + c + 2xy

#3 = Apply the "inverse property of addition".

• 4x + ( 1 - 3 ) × y + c + 2xy → 4x - 2y + c + 2xy

hope it helps
