Hi

six more cars then 18 wheel trucks. 

Let x and (x+6) represent the number of 18-wheel trucks and cars respectively

Question states*** 134 'wheels' in parking lot altogether

 18x + 4(x+6) = 134

Solving for x

       22x = 110

         x = 5, number of trucks.  there were 11 cars (5+6)

CHECKING our Answer***

  5*18 + 4*11 = 90 + 44 = 134 wheels
