The Sum Of Two Numbers Is 66 And Their Difference Is 1

The problem given says that 2 unknown numbers are given, whose sum is equal to 66 and the difference is 1. Let's find the two numbers :

When we add the two numbers :
X + Y = 66

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 = 66
X - Y = 1

2X = 67

Let's divide 67 to 2 for the first number "X" .

X/2 = 33.5

First number is 33.5

X + Y = 66
So ;
33.5 + Y = 66
Y = 66 - 33.5
Y = 32.5

Second number is 32.5

Question & Answer
The Sum Of Two Numbers Is 66 And Their Difference Is 1 : 33.5 And 32.5
