The Sum Of Two Numbers Is 56 And Their Difference Is 4

The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 4. Let's find the two numbers :

When we add the two numbers :
X + Y = 56

The difference of two numbers :
X - Y = 4

Solution :

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

X + Y = 56
X - Y = 4

2X = 60

Let's divide 60 to 2 for the first number "X" .

X/2 = 30

First number is 30

X + Y = 56
So ;
30 + Y = 56
Y = 56 - 30
Y = 26

Second number is 26
