Ksenya-84 [330]

Answer:

$-x-3$

Step-by-step explanation:

They want you to simplify the expression.

Step 1: Apply the distributive property.

$\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)$

Step 2: Cancel the common factor of 5.

$x+\frac{1}{5} (-15-2x)$

Step 3: Cancel the common factor of 5.

$x-3-2x$

Step 4: Subtract 2x from x.

$-x-3$
