The Sum Of Two Numbers Is 19 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 19 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 19
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 19 X - Y = 8 2X = 27 |
Let's divide 27 to 2 for the first number "X" .
X/2 = 13.5
First number is 13.5
X + Y = 19
So ;
13.5 + Y = 19
Y = 19 - 13.5
Y = 5.5
Second number is 5.5
Question & Answer
The Sum Of Two Numbers Is 19 And Their Difference Is 8 : 13.5 And 5.5
