The Sum Of Two Numbers Is 27 And Their Difference Is 1

The problem given says that 2 unknown numbers are given, whose sum is equal to 27 and the difference is 1. Let's find the two numbers :

When we add the two numbers :
X + Y = 27

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 = 27
X - Y = 1

2X = 28

Let's divide 28 to 2 for the first number "X" .

X/2 = 14

First number is 14

X + Y = 27
So ;
14 + Y = 27
Y = 27 - 14
Y = 13

Second number is 13
