The Sum Of Two Numbers Is 74 And Their Difference Is 23
The problem given says that 2 unknown numbers are given, whose sum is equal to 74 and the difference is 23. Let's find the two numbers :When we add the two numbers :
X + Y = 74
The difference of two numbers :
X - Y = 23
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 74 X - Y = 23 2X = 97 |
Let's divide 97 to 2 for the first number "X" .
X/2 = 48.5
First number is 48.5
X + Y = 74
So ;
48.5 + Y = 74
Y = 74 - 48.5
Y = 25.5
Second number is 25.5
Question & Answer
