The Sum Of Two Numbers Is 22 And Their Difference Is 2

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

When we add the two numbers :
X + Y = 22

The difference of two numbers :
X - Y = 2

Solution :

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

X + Y = 22
X - Y = 2

2X = 24

Let's divide 24 to 2 for the first number "X" .

X/2 = 12

First number is 12

X + Y = 22
So ;
12 + Y = 22
Y = 22 - 12
Y = 10

Second number is 10
