Explanation:
Let's denote the two numbers by x and y. We know that:
The quotient of two numbers is 1, which means x/y = 1, or equivalently x=y.
The sum of the two numbers is 86, which means x + y = 86.
Substituting x for y in the second equation, we get:
x + x = 86
Simplifying, we get:
2x = 86
Dividing both sides by 2, we get:
x = 43
Since x=y, the other number is also 43.
Therefore, the two numbers are 43 and 43.
