The Sum Of Two Numbers Is 63 And Their Difference Is 37

The problem given says that 2 unknown numbers are given, whose sum is equal to 63 and the difference is 37. Let's find the two numbers :

When we add the two numbers :
X + Y = 63

The difference of two numbers :
X - Y = 37

Solution :

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

X + Y = 63
X - Y = 37

2X = 100

Let's divide 100 to 2 for the first number "X" .

X/2 = 50

First number is 50

X + Y = 63
So ;
50 + Y = 63
Y = 63 - 50
Y = 13

Second number is 13
