The Sum Of Two Numbers Is 64 And Their Difference Is 34

The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 34. Let's find the two numbers :

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

The difference of two numbers :
X - Y = 34

Solution :

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

X + Y = 64
X - Y = 34

2X = 98

Let's divide 98 to 2 for the first number "X" .

X/2 = 49

First number is 49

X + Y = 64
So ;
49 + Y = 64
Y = 64 - 49
Y = 15

Second number is 15
