The Sum Of Two Numbers Is 65 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 65 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 65
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 65 X - Y = 18 2X = 83 |
Let's divide 83 to 2 for the first number "X" .
X/2 = 41.5
First number is 41.5
X + Y = 65
So ;
41.5 + Y = 65
Y = 65 - 41.5
Y = 23.5
Second number is 23.5
Question & Answer
The Sum Of Two Numbers Is 65 And Their Difference Is 18 : 41.5 And 23.5
