The Sum Of Two Numbers Is 47 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 47 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 47
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 47 X - Y = 8 2X = 55 |
Let's divide 55 to 2 for the first number "X" .
X/2 = 27.5
First number is 27.5
X + Y = 47
So ;
27.5 + Y = 47
Y = 47 - 27.5
Y = 19.5
Second number is 19.5
Question & Answer
