Answer:  b)  x = 6 and total line is 52

                c)  x = 5.5 and total line is 20

Step-by-step explanation:

b) (x+20) = (5x-4)

   4x = 24

     x = 6

     Line (x+20) = 26

     Line (5x-4) = 26

Total line = 52

  c)  (4x-12) = (-2x+21)

          6x = 33

           x = 5.5

      Line (4x+12) = 10.0

      Line (-2x+21) = 10.0

Total line = 20
