1.2/3-3p =2p+7
      2/3-7= 5p
 2/3-21/3 = 5p
-19/3      = 5p
    -19/15= p
2.2/5 (4p-6)=2p +7
 8/5p - 12/5=2p+7
8/5p-2p     = 7 + 12/5
8/5p - 10/5p = 35/5 + 12/5
-2/5p           = 47/5
       p         = -23.5

3.3/5 (2p-6) = 5/3(p+7)
    6/5p - 18/5 = 5/3p + 35/3
    6/5p-5/3p = 35/3 + 18/5
     -7/15p     = 229/15
                p = - 3435/105
