The Sum Of Two Numbers Is 50 And Their Difference Is 4

The problem given says that 2 unknown numbers are given, whose sum is equal to 50 and the difference is 4. Let's find the two numbers :

When we add the two numbers :
X + Y = 50

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 = 50
X - Y = 4

2X = 54

Let's divide 54 to 2 for the first number "X" .

X/2 = 27

First number is 27

X + Y = 50
So ;
27 + Y = 50
Y = 50 - 27
Y = 23

Second number is 23
