The Sum Of Two Numbers Is 64 And Their Difference Is 16

The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 16. Let's find the two numbers :

When we add the two numbers :
X + Y = 64

The difference of two numbers :
X - Y = 16

Solution :

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

X + Y = 64
X - Y = 16

2X = 80

Let's divide 80 to 2 for the first number "X" .

X/2 = 40

First number is 40

X + Y = 64
So ;
40 + Y = 64
Y = 64 - 40
Y = 24

Second number is 24
