The Sum Of Two Numbers Is 63 And Their Difference Is 25

The problem given says that 2 unknown numbers are given, whose sum is equal to 63 and the difference is 25. Let's find the two numbers :

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

The difference of two numbers :
X - Y = 25

Solution :

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

X + Y = 63
X - Y = 25

2X = 88

Let's divide 88 to 2 for the first number "X" .

X/2 = 44

First number is 44

X + Y = 63
So ;
44 + Y = 63
Y = 63 - 44
Y = 19

Second number is 19
