The Sum Of Two Numbers Is 64 And Their Difference Is 36
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 36. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 36
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 64 X - Y = 36 2X = 100 |
Let's divide 100 to 2 for the first number "X" .
X/2 = 50
First number is 50
X + Y = 64
So ;
50 + Y = 64
Y = 64 - 50
Y = 14
Second number is 14
Question & Answer
