The Sum Of Two Numbers Is 13 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 13 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 13
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 13 X - Y = 3 2X = 16 |
Let's divide 16 to 2 for the first number "X" .
X/2 = 8
First number is 8
X + Y = 13
So ;
8 + Y = 13
Y = 13 - 8
Y = 5
Second number is 5
Question & Answer
