The Sum Of Two Numbers Is 52 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 52 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 52
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 52 X - Y = 12 2X = 64 |
Let's divide 64 to 2 for the first number "X" .
X/2 = 32
First number is 32
X + Y = 52
So ;
32 + Y = 52
Y = 52 - 32
Y = 20
Second number is 20
Question & Answer
