The Sum Of Two Numbers Is 54 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 54 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 54
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 54 X - Y = 5 2X = 59 |
Let's divide 59 to 2 for the first number "X" .
X/2 = 29.5
First number is 29.5
X + Y = 54
So ;
29.5 + Y = 54
Y = 54 - 29.5
Y = 24.5
Second number is 24.5
Question & Answer
