The Sum Of Two Numbers Is 42 And Their Difference Is 22

The problem given says that 2 unknown numbers are given, whose sum is equal to 42 and the difference is 22. Let's find the two numbers :

When we add the two numbers :
X + Y = 42

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 = 42
X - Y = 22

2X = 64

Let's divide 64 to 2 for the first number "X" .

X/2 = 32

First number is 32

X + Y = 42
So ;
32 + Y = 42
Y = 42 - 32
Y = 10

Second number is 10
