The Sum Of Two Numbers Is 64 And Their Difference Is 1

The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 1. Let's find the two numbers :

When we add the two numbers :
X + Y = 64

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 = 64
X - Y = 1

2X = 65

Let's divide 65 to 2 for the first number "X" .

X/2 = 32.5

First number is 32.5

X + Y = 64
So ;
32.5 + Y = 64
Y = 64 - 32.5
Y = 31.5

Second number is 31.5

Question & Answer
The Sum Of Two Numbers Is 64 And Their Difference Is 1 : 32.5 And 31.5
