The Sum Of Two Numbers Is 72 And Their Difference Is 16
The problem given says that 2 unknown numbers are given, whose sum is equal to 72 and the difference is 16. Let's find the two numbers :When we add the two numbers :
X + Y = 72
The difference of two numbers :
X - Y = 16
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 72 X - Y = 16 2X = 88 |
Let's divide 88 to 2 for the first number "X" .
X/2 = 44
First number is 44
X + Y = 72
So ;
44 + Y = 72
Y = 72 - 44
Y = 28
Second number is 28
Question & Answer
