The Sum Of Two Numbers Is 41 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 41 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 41
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 41 X - Y = 2 2X = 43 |
Let's divide 43 to 2 for the first number "X" .
X/2 = 21.5
First number is 21.5
X + Y = 41
So ;
21.5 + Y = 41
Y = 41 - 21.5
Y = 19.5
Second number is 19.5
Question & Answer
The Sum Of Two Numbers Is 41 And Their Difference Is 2 : 21.5 And 19.5
