The Sum Of Two Numbers Is 67 And Their Difference Is 22

The problem given says that 2 unknown numbers are given, whose sum is equal to 67 and the difference is 22. Let's find the two numbers :

When we add the two numbers :
X + Y = 67

The difference of two numbers :
X - Y = 22

Solution :

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

X + Y = 67
X - Y = 22

2X = 89

Let's divide 89 to 2 for the first number "X" .

X/2 = 44.5

First number is 44.5

X + Y = 67
So ;
44.5 + Y = 67
Y = 67 - 44.5
Y = 22.5

Second number is 22.5

Question & Answer
