The Sum Of Two Numbers Is 65 And Their Difference Is 8

The problem given says that 2 unknown numbers are given, whose sum is equal to 65 and the difference is 8. Let's find the two numbers :

When we add the two numbers :
X + Y = 65

The difference of two numbers :
X - Y = 8

Solution :

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

X + Y = 65
X - Y = 8

2X = 73

Let's divide 73 to 2 for the first number "X" .

X/2 = 36.5

First number is 36.5

X + Y = 65
So ;
36.5 + Y = 65
Y = 65 - 36.5
Y = 28.5

Second number is 28.5
