The Sum Of Two Numbers Is 40 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 40 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 40
The difference of two numbers :
X - Y = 26
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 40 X - Y = 26 2X = 66 |
Let's divide 66 to 2 for the first number "X" .
X/2 = 33
First number is 33
X + Y = 40
So ;
33 + Y = 40
Y = 40 - 33
Y = 7
Second number is 7
Question & Answer
