The Sum Of Two Numbers Is 41 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 41 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 41
The difference of two numbers :
X - Y = 37
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 41 X - Y = 37 2X = 78 |
Let's divide 78 to 2 for the first number "X" .
X/2 = 39
First number is 39
X + Y = 41
So ;
39 + Y = 41
Y = 41 - 39
Y = 2
Second number is 2
