The Sum Of Two Numbers Is 43 And Their Difference Is 22

The problem given says that 2 unknown numbers are given, whose sum is equal to 43 and the difference is 22. Let's find the two numbers :

When we add the two numbers :
X + Y = 43

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 = 43
X - Y = 22

2X = 65

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

X/2 = 32.5

First number is 32.5

X + Y = 43
So ;
32.5 + Y = 43
Y = 43 - 32.5
Y = 10.5

Second number is 10.5

Question & Answer
The Sum Of Two Numbers Is 43 And Their Difference Is 22 : 32.5 And 10.5
