The Sum Of Two Numbers Is 40 And Their Difference Is 33
The problem given says that 2 unknown numbers are given, whose sum is equal to 40 and the difference is 33. Let's find the two numbers :When we add the two numbers :
X + Y = 40
The difference of two numbers :
X - Y = 33
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 40 X - Y = 33 2X = 73 |
Let's divide 73 to 2 for the first number "X" .
X/2 = 36.5
First number is 36.5
X + Y = 40
So ;
36.5 + Y = 40
Y = 40 - 36.5
Y = 3.5
Second number is 3.5
Question & Answer
