The Sum Of Two Numbers Is 69 And Their Difference Is 22

The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 22. Let's find the two numbers :

When we add the two numbers :
X + Y = 69

The difference of two numbers :
X - Y = 22

Solution :

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

X + Y = 69
X - Y = 22

2X = 91

Let's divide 91 to 2 for the first number "X" .

X/2 = 45.5

First number is 45.5

X + Y = 69
So ;
45.5 + Y = 69
Y = 69 - 45.5
Y = 23.5

Second number is 23.5

Question & Answer
The Sum Of Two Numbers Is 69 And Their Difference Is 22 : 45.5 And 23.5
