$- 6 y^{2} + 9 y^{2} - y - 9 - 7 y^{2} + 1 + 10 y + 3 y$

Step 1

Add $- 6 y^{2}$ and $9 y^{2}$ .

$3 y^{2} - y - 9 - 7 y^{2} + 1 + 10 y + 3 y$

Step 2

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

$- 4 y^{2} - y - 9 + 1 + 10 y + 3 y$

Step 3

Add $- y$ and $10 y$ .

$- 4 y^{2} + 9 y - 9 + 1 + 3 y$

Step 4

Add $9 y$ and $3 y$ .

$- 4 y^{2} + 12 y - 9 + 1$

Step 5

Add $- 9$ and $1$ .

$- 4 y^{2} + 12 y - 8$
