The Sum Of Two Numbers Is 10 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 10 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 10
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 = 10 X - Y = 3 2X = 13 |
Let's divide 13 to 2 for the first number "X" .
X/2 = 6.5
First number is 6.5
X + Y = 10
So ;
6.5 + Y = 10
Y = 10 - 6.5
Y = 3.5
Second number is 3.5
Question & Answer
