The Sum Of Two Numbers Is 60 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 60 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 60
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 60 X - Y = 5 2X = 65 |
Let's divide 65 to 2 for the first number "X" .
X/2 = 32.5
First number is 32.5
X + Y = 60
So ;
32.5 + Y = 60
Y = 60 - 32.5
Y = 27.5
Second number is 27.5
Question & Answer
The Sum Of Two Numbers Is 60 And Their Difference Is 5 : 32.5 And 27.5
