Answer:

<h2>Santa ate one sugar cookie and 1 chocolate chip cookies.</h2>

Step-by-step explanation:

We know that

<h3>Santa ate the same number of sugar cookies and chocolate chip cookies.</h3>

If $x$ represents sugar cookies, and $y$ represents chocolate chip cookies.

This part of the problem is expressed as

$x=y$

Because Santa ate the same of each type.

<h3>Twice the number of sugar cookies he ate decreased by one equals the number of chocolate chip cookies.</h3>

Now, this part of the problem is expressed

$2x-1=y$

Because twice of sugar cookies decreased by one is equals to chocolate chip cookies.

Replacing the first equation into the second one, we have

$2x-1=x\\2x-x=1\\x=1$

Now, replacing this value in the first equation, we have

$y=1$

Therefore, Santa ate one sugar cookie and 1 chocolate chip cookies.
