$7 x y^{3} - 5 x y^{2} - 3 y - 2 x y^{3} - 8 x y^{2} + 12 y + 9$

Step 1

Subtract $2 x y^{3}$ from $7 x y^{3}$ .

$5 x y^{3} - 5 x y^{2} - 3 y - 8 x y^{2} + 12 y + 9$

Step 2

Subtract $8 x y^{2}$ from $- 5 x y^{2}$ .

$5 x y^{3} - 13 x y^{2} - 3 y + 12 y + 9$

Step 3

Add $- 3 y$ and $12 y$ .

$5 x y^{3} - 13 x y^{2} + 9 y + 9$
