Total age
<span>6 * 27 </span>
<span>162 </span>
<span>Subtotal age of first 4 </span>
<span>4 * 23 </span>
<span>92 </span>

<span>102 </span>
<span>In the total of the first 4 and last 3 </span>
<span>the 4th person has been counted twice. </span>
<span>This second time must be subtracted. </span>
<span>Therefor </span>
<span>92 + 102 - x = 162 </span>
<span>194 - x = 162 </span>
<span>Subtract 194 from both sides </span>
<span>-x = -32 </span>
<span>Multiply both sides by -1 </span>
<span>x = 32
