Total tickets sold: at least 168 symbolically: ≥168

He sold 4 more adult tickets than children tickets.

Let x represent the number of children tickets he he sold, then x+4 will represent the number of adult tickets he sold.

The total tickets sold is equal to the sum of the number of children tickes and the number of adults tickets, symbolically:

x+(x+4)≥168

From this expression you can clear the value of x

$\begin{gathered} x+(x+4)\ge168 \\ x+x+4\ge168 \\ 2x\ge168-4 \\ 2x\ge164 \\ x\ge(164)/(2) \\ x\ge82 \end{gathered}$

The minimum amount of children's tickets he could've sold is 82.
