Commutativity or the Abelian property.
yes
p + 7 = 13 p = 6
p + 7 = 111 subtract 7 from each side p + 7 - 7 = 111 - 7 p = 104
p is obviously zero because any number x plus 0 equals itself.

3p plus 7 equals 34, where P is equivalent to number 9.

p=3 !
(p + 12)(p - 7) p = 7, -12
-6
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
3p+7 = 16+2p 3p-2p = 16-7 p = 9
