The Sum Of Two Numbers Is 25 And Their Difference Is 1

The problem given says that 2 unknown numbers are given, whose sum is equal to 25 and the difference is 1. Let's find the two numbers :

When we add the two numbers :
X + Y = 25

The difference of two numbers :
X - Y = 1

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 25
X - Y = 1

2X = 26

Let's divide 26 to 2 for the first number "X" .

X/2 = 13

First number is 13

X + Y = 25
So ;
13 + Y = 25
Y = 25 - 13
Y = 12

Second number is 12
