The Sum Of Two Numbers Is 39 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 39 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 39
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 39 X - Y = 14 2X = 53 |
Let's divide 53 to 2 for the first number "X" .
X/2 = 26.5
First number is 26.5
X + Y = 39
So ;
26.5 + Y = 39
Y = 39 - 26.5
Y = 12.5
Second number is 12.5
Question & Answer
