The Sum Of Two Numbers Is 41 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 41 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 41
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 41 X - Y = 10 2X = 51 |
Let's divide 51 to 2 for the first number "X" .
X/2 = 25.5
First number is 25.5
X + Y = 41
So ;
25.5 + Y = 41
Y = 41 - 25.5
Y = 15.5
Second number is 15.5
Question & Answer
