7p - 4 + 12p = -3(5 + p)
7p - 4 + 12p = -15 - 3p
        + 4              + 4
7p + 12p    = -11 - 3p
        + 3p                + 3p
22p             = -11

p = -1/2  Answer

Hi Tnt82799, 

7p - 4 + 12p = - 3(5 + p)
7p + 12p - 4 = - 15 - 3p
19p + 3p = - 15 + 4
22p = - 11
p = - 11 / 22
p = - 1 / 2

S = {- 1 / 2}
