The Sum Of Two Numbers Is 47 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 47 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 47
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 = 47 X - Y = 9 2X = 56 |
Let's divide 56 to 2 for the first number "X" .
X/2 = 28
First number is 28
X + Y = 47
So ;
28 + Y = 47
Y = 47 - 28
Y = 19
Second number is 19
Question & Answer
