The Sum Of Two Numbers Is 68 And Their Difference Is 6
The problem given says that 2 unknown numbers are given, whose sum is equal to 68 and the difference is 6. Let's find the two numbers :When we add the two numbers :
X + Y = 68
The difference of two numbers :
X - Y = 6
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 68 X - Y = 6 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 68
So ;
37 + Y = 68
Y = 68 - 37
Y = 31
Second number is 31
Question & Answer
