14 + 6p = 6 + 7p 8 = p
7p plus 6p equals 13p. You simply combine the like terms by adding the coefficients (7 and 6) together. Therefore, the equation simplifies to 13p.
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
-31=8-6p-7p -31=8-13p ==add the -6p and the - 7p together -39=13p =======move the 8 over to the other side p=3 =======divide both sides by 13 to get p by itself
8p+5 = 11+7p= 8p-7p = 11-5p = 6
