6 small dolls + 5 large dolls = $65<em> ------------------ (1) </em>
5 small dolls + 4 large dolls = $53 <em>------------------ (2)</em>

<em>(1) x 5 : </em>30 small dolls + 25 large dolls = $325<span> <em>------------------ (1a)</em></span><em> </em>
<em>(2) x 6 : </em>30 small dolls + 24 large dolls = $318<em> ------------------ (2a)</em>

<em>(1a) - (2a) :</em> 1 large doll = $7

<em>Substitute 1 large doll = $7 into (1):</em>

6 small dolls + 5(7)  = $65
6 small dolls + 35  = $65
6 small dolls = $65 - $35
6 small dolls = $30
1 small doll  = $5

Answer: 1 small doll is $5 and I large doll is $7.
