(6x18)+(6x1)=115
19 * 14 = (20 - 1) * 14 = 20*14 - 1*14 = 280 - 14 = 266

19*14 = 19*(10 + 4) = 19*10 + 19*4 = 190 + 76 = 266 (You could use the distributive property again to split 19 into 10 + 9 but that is multiplying by 19 is simple enough and using the distributive property for that is just laziness.
The Abelian (commutative) property of integers under addition.
220 x 19 = (220 x 10) + (220 x 9)
(6x18)+(6x1)=115
An equation where p = 19
Commutative property of addition.
a=10
An equation where x equals 3.
19 * 14 = (20 - 1) * 14 = 20*14 - 1*14 = 280 - 14 = 266
19*70 = (20 - 1)*70 = 20*70 - 1*70 = 1400 - 70 = 1330
Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19
