Question

Find two consecutive integers whose sum is equal 129.

Answer 1

Taking the first number as x and the second number as y, which being the consecutive number after x, will be x+1, we get the equation as,
x+(x+1) = 129
or 2x+1=129
2x=129−1

x=128/2

x=64

So the given two numbers are,
The first number is 64 and the second number is y = 65.
