The Sum Of Two Numbers Is 48 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 48 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 48
The difference of two numbers :
X - Y = 9
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 48 X - Y = 9 2X = 57 |
Let's divide 57 to 2 for the first number "X" .
X/2 = 28.5
First number is 28.5
X + Y = 48
So ;
28.5 + Y = 48
Y = 48 - 28.5
Y = 19.5
Second number is 19.5
Question & Answer
