The Sum Of Two Numbers Is 85 And Their Difference Is 36
The problem given says that 2 unknown numbers are given, whose sum is equal to 85 and the difference is 36. Let's find the two numbers :When we add the two numbers :
X + Y = 85
The difference of two numbers :
X - Y = 36
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 85 X - Y = 36 2X = 121 |
Let's divide 121 to 2 for the first number "X" .
X/2 = 60.5
First number is 60.5
X + Y = 85
So ;
60.5 + Y = 85
Y = 85 - 60.5
Y = 24.5
Second number is 24.5
Question & Answer
The Sum Of Two Numbers Is 85 And Their Difference Is 36 : 60.5 And 24.5
