The Sum Of Two Numbers Is 30 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 30 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 30
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 30 X - Y = 14 2X = 44 |
Let's divide 44 to 2 for the first number "X" .
X/2 = 22
First number is 22
X + Y = 30
So ;
22 + Y = 30
Y = 30 - 22
Y = 8
Second number is 8
Question & Answer
