Hi,

  R___________S______________T



if RT=21 AND ST=8, calculate RS = 13

 IF RS=17 AND ST=34,calculate RT = 51

 If RT=25 RS=x+8 and ST=3X+5, calculate ST  

      25-(x+8)= 3x+5

           12 = 4x, 

              x =3  and ST = 3x+5 = 14 

 IF S is the midpoint of line RT, RS=5X+4 AND ST=3X+6 calculate RT

               5x + 4 = 3x+ 6

                   2x = 2

                    x = 1 and  5x+4+3x+6 = 18
