The Sum Of Two Numbers Is 59 And Their Difference Is 22

The problem given says that 2 unknown numbers are given, whose sum is equal to 59 and the difference is 22. Let's find the two numbers :

When we add the two numbers :
X + Y = 59

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 = 59
X - Y = 22

2X = 81

Let's divide 81 to 2 for the first number "X" .

X/2 = 40.5

First number is 40.5

X + Y = 59
So ;
40.5 + Y = 59
Y = 59 - 40.5
Y = 18.5

Second number is 18.5

Question & Answer
The Sum Of Two Numbers Is 59 And Their Difference Is 22 : 40.5 And 18.5
