Answer:

The number of counties in state A are 70.

The number of counties in state B are 68.

Explanation:

The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138.

Let the two consecutive even integers be x and x+2.

As their sum is 138, we can denote this mathematically as :


x+x+2=138


=> 2x+2=138


=> 2x=138-2


=> 2x=136

Now, we get x = 68

And
x+2=68+2 = 70

Hence, the two numbers are 68 and 70.

So, the number of counties in state A are 70.

The number of counties in state B are 68.
