The Sum Of Two Numbers Is 52 And Their Difference Is 13

The problem given says that 2 unknown numbers are given, whose sum is equal to 52 and the difference is 13. Let's find the two numbers :

When we add the two numbers :
X + Y = 52

The difference of two numbers :
X - Y = 13

Solution :

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

X + Y = 52
X - Y = 13

2X = 65

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

X/2 = 32.5

First number is 32.5

X + Y = 52
So ;
32.5 + Y = 52
Y = 52 - 32.5
Y = 19.5

Second number is 19.5

Question & Answer
The Sum Of Two Numbers Is 52 And Their Difference Is 13 : 32.5 And 19.5
