The Sum Of Two Numbers Is 19 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 19 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 19
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 = 19 X - Y = 3 2X = 22 |
Let's divide 22 to 2 for the first number "X" .
X/2 = 11
First number is 11
X + Y = 19
So ;
11 + Y = 19
Y = 19 - 11
Y = 8
Second number is 8
Question & Answer
