Step-by-step explanation:

Perimeter is equal to twice the length plus twice the width

      Perimeter = 2L + 2W        factoring out the 2

      Perimeter = 2(L + W)       L = (8x + 5 - 3x)    W = (4x - 1)    

                                               first I would simplify L    collecting the terms of x

                                                L = (5x + 5)

      plug in to L and W    

      Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 ))            L = (8x + 5 - 3x)    W = (4x - 1)

      Perimeter = 2 ( 5x + 4x + 5 -1 )                 collect like terms

      Perimeter = 2 (  9x +4)                                    2 times the 9 and 4

      Perimeter = 18x + 8                            SOLVE for x

      Perimeter - 8 = 18x + 8 -8

      Perimeter - 8 = 18x

      (Perimeter - 8) / 18 = 18x / 18

      (Perimeter - 8) / 18  =  x

remember the Perimeter equals 88

       (88 - 8) / 18  =  x units                    

             4.444444444  units   =  x      

This seems like an odd number so let's it

    Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 ))

    Perimeter = 2 (( 5(4.444) + 5 ) + ( 4(4.444) - 1 ))   = 87.9952

                  close enough with the rounding off error
