The Sum Of Two Numbers Is 52 And Their Difference Is 25
The problem given says that 2 unknown numbers are given, whose sum is equal to 52 and the difference is 25. Let's find the two numbers :When we add the two numbers :
X + Y = 52
The difference of two numbers :
X - Y = 25
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 52 X - Y = 25 2X = 77 |
Let's divide 77 to 2 for the first number "X" .
X/2 = 38.5
First number is 38.5
X + Y = 52
So ;
38.5 + Y = 52
Y = 52 - 38.5
Y = 13.5
Second number is 13.5
Question & Answer
