The Sum Of Two Numbers Is 67 And Their Difference Is 26

The problem given says that 2 unknown numbers are given, whose sum is equal to 67 and the difference is 26. Let's find the two numbers :

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

The difference of two numbers :
X - Y = 26

Solution :

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

X + Y = 67
X - Y = 26

2X = 93

Let's divide 93 to 2 for the first number "X" .

X/2 = 46.5

First number is 46.5

X + Y = 67
So ;
46.5 + Y = 67
Y = 67 - 46.5
Y = 20.5

Second number is 20.5

Question & Answer
The Sum Of Two Numbers Is 67 And Their Difference Is 26 : 46.5 And 20.5
