The Sum Of Two Numbers Is 67 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 67 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 67
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 67 X - Y = 17 2X = 84 |
Let's divide 84 to 2 for the first number "X" .
X/2 = 42
First number is 42
X + Y = 67
So ;
42 + Y = 67
Y = 67 - 42
Y = 25
Second number is 25
Question & Answer
