because it reduces the expressions to one expression.

The distributive property is important when simplifying expressions. It is useful when you are trying to simplify for a variable that is inside a set of parentheses. Some examples are:
2(x+4)=3(x-1)
2x + 8 = 3x-3
-2x + 3 =-2x+3
11 = x
Then you can check your work by plugging in the number.
2(11+4) = 3(11-1)
2(15) = 3(10)
30 = 30

For ex:
2(2+3)= Y
Distributive property simplifys it.
(2x2)+(2x3)=Y
4+6=Y
so then:
10=Y
If it was not for the distributive property then it would be:
(2+3)+(2+3)=Y
5+(2+3)=Y
5+5=Y
10=Y
This was simply but if it were to have been a problem such as:
2[76(3*4)-2(56*34)]+67*24=Y
Then it would REALLY be a pain.

put the same variable in out side the groups. also the number too.
exp
(2x+2xY)
u can make it
2x(1+y)
