The sum of two consecutive Integers are 199. Find the Integers
Yanka [14]

Answer:

99 and 100.

Step-by-step explanation:

Let's say the lower number is x. This means that the bigger number would be x+1

x+x+1=199

Simplify

2x+1=199

Subtract 1 on each side of the equation to isolate 2x:

2x=198

Divide

x=99

Let's put this to the test! The lower number(x) is 99, and the bigger number(x+1) would be 100. The total is 199.

Happy learning!
