What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

Number of members = 100

And, It contains 20 more Democrat's than Republicans.

Now, Let number of Democrat's does it contain = x

Then, Number of Republicans does it contain = x - 20

Since, Number of members = 100

Hence, We can formulate;

⇒ x + (x - 20) = 100

⇒ 2x = 100 + 20

⇒ 2x = 120

⇒ x = 60

Thus, Number of Democrat's does it contain = 60

100=d+(d-20)
First add 20 to both sides.  
120=d+d
Now divide the sides by 2.
D=60
There are 60 democrats.
100=60+(60-20)
100=60+40

there are 60 democrats and 40 republicans
