The Sum Of Two Numbers Is 67 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 67 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 67
The difference of two numbers :
X - Y = 9
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 67 X - Y = 9 2X = 76 |
Let's divide 76 to 2 for the first number "X" .
X/2 = 38
First number is 38
X + Y = 67
So ;
38 + Y = 67
Y = 67 - 38
Y = 29
Second number is 29
Question & Answer
