The Sum Of Two Numbers Is 65 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 65 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 65
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 = 65 X - Y = 9 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 65
So ;
37 + Y = 65
Y = 65 - 37
Y = 28
Second number is 28
Question & Answer
