Step 1.2.1

Multiply $2$ by $- 1$ .

$5 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 (z^{4} y) - (3 z) - (- 2 z y^{3}) - (2 z y^{2})$

Step 1.2.2

Multiply $3$ by $- 1$ .

$5 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 (z^{4} y) - 3 z - (- 2 z y^{3}) - (2 z y^{2})$

Step 1.2.3

Multiply $- 2$ by $- 1$ .

$5 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 (z^{4} y) - 3 z + 2 (z y^{3}) - (2 z y^{2})$

Step 1.2.4

Multiply $2$ by $- 1$ .

$5 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 (z^{4} y) - 3 z + 2 (z y^{3}) - 2 (z y^{2})$

Step 1.3

Remove parentheses.

$5 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 z^{4} y - 3 z + 2 z y^{3} - 2 z y^{2}$

Step 2

Simplify by adding terms.

Step 2.1

Subtract $2 z y^{2}$ from $5 z y^{2}$ .

$3 z y^{2} - 3 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 2 z^{4} y - 3 z + 2 z y^{3}$

Step 2.2

Subtract $2 z^{4} y$ from $- 3 z^{4} y$ .

$3 z y^{2} - 5 z^{4} y + 7 z y^{3} + 7 z y^{3} + 2 z - 3 z + 2 z y^{3}$

Step 2.3

Add $7 z y^{3}$ and $7 z y^{3}$ .

$3 z y^{2} - 5 z^{4} y + 14 z y^{3} + 2 z - 3 z + 2 z y^{3}$

Step 2.4

Add $14 z y^{3}$ and $2 z y^{3}$ .

$3 z y^{2} - 5 z^{4} y + 16 z y^{3} + 2 z - 3 z$

Step 2.5

Subtract $3 z$ from $2 z$ .

$3 z y^{2} - 5 z^{4} y + 16 z y^{3} - z$
