Hi,         
An adult ticket costs $2 more than a child ticket
Let x and (x + $2)represent the cost of the child and adult ticket respectively
Question states***
 2(x+ $2) + 3x = $34
solving for x
 2x+ $4 + 3x = $34
        5x = $30
         x = $6 , the cost of the child ticket.  Adult ticket is $8   ($6+$2)

CHECKING our Answer***
  2*$8  + 3*$6 = $16 + $18 = $34
