The Sum Of Two Numbers Is 69 And Their Difference Is 23

The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 23. Let's find the two numbers :

When we add the two numbers :
X + Y = 69

The difference of two numbers :
X - Y = 23

Solution :

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

X + Y = 69
X - Y = 23

2X = 92

Let's divide 92 to 2 for the first number "X" .

X/2 = 46

First number is 46

X + Y = 69
So ;
46 + Y = 69
Y = 69 - 46
Y = 23

Second number is 23
