The Sum Of Two Numbers Is 61 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 61 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 61
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 = 61 X - Y = 10 2X = 71 |
Let's divide 71 to 2 for the first number "X" .
X/2 = 35.5
First number is 35.5
X + Y = 61
So ;
35.5 + Y = 61
Y = 61 - 35.5
Y = 25.5
Second number is 25.5
Question & Answer
The Sum Of Two Numbers Is 61 And Their Difference Is 10 : 35.5 And 25.5
