Basic Math Examples

$2 n - 5 (4 y - 2 n) - 5 y$

Step 1

Apply the distributive property.

$2 n - 5 (4 y) - 5 (- 2 n) - 5 y$

Step 2

Multiply $4$ by $- 5$ .

$2 n - 20 y - 5 (- 2 n) - 5 y$

Step 3

Multiply $- 2$ by $- 5$ .

$2 n - 20 y + 10 n - 5 y$

Step 4

Add $2 n$ and $10 n$ .

$12 n - 20 y - 5 y$

Step 5

Subtract $5 y$ from $- 20 y$ .

$12 n - 25 y$
