The Sum Of Two Numbers Is 41 And Their Difference Is 15

The problem given says that 2 unknown numbers are given, whose sum is equal to 41 and the difference is 15. Let's find the two numbers :

When we add the two numbers :
X + Y = 41

The difference of two numbers :
X - Y = 15

Solution :

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

X + Y = 41
X - Y = 15

2X = 56

Let's divide 56 to 2 for the first number "X" .

X/2 = 28

First number is 28

X + Y = 41
So ;
28 + Y = 41
Y = 41 - 28
Y = 13

Second number is 13
