The Sum Of Two Numbers Is 43 And Their Difference Is 27
The problem given says that 2 unknown numbers are given, whose sum is equal to 43 and the difference is 27. Let's find the two numbers :When we add the two numbers :
X + Y = 43
The difference of two numbers :
X - Y = 27
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 43 X - Y = 27 2X = 70 |
Let's divide 70 to 2 for the first number "X" .
X/2 = 35
First number is 35
X + Y = 43
So ;
35 + Y = 43
Y = 43 - 35
Y = 8
Second number is 8
Question & Answer
