The Sum Of Two Numbers Is 41 And Their Difference Is 31
The problem given says that 2 unknown numbers are given, whose sum is equal to 41 and the difference is 31. Let's find the two numbers :When we add the two numbers :
X + Y = 41
The difference of two numbers :
X - Y = 31
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 41 X - Y = 31 2X = 72 |
Let's divide 72 to 2 for the first number "X" .
X/2 = 36
First number is 36
X + Y = 41
So ;
36 + Y = 41
Y = 41 - 36
Y = 5
Second number is 5
