The Sum Of Two Numbers Is 82 And Their Difference Is 19
The problem given says that 2 unknown numbers are given, whose sum is equal to 82 and the difference is 19. Let's find the two numbers :When we add the two numbers :
X + Y = 82
The difference of two numbers :
X - Y = 19
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 82 X - Y = 19 2X = 101 |
Let's divide 101 to 2 for the first number "X" .
X/2 = 50.5
First number is 50.5
X + Y = 82
So ;
50.5 + Y = 82
Y = 82 - 50.5
Y = 31.5
Second number is 31.5
Question & Answer
The Sum Of Two Numbers Is 82 And Their Difference Is 19 : 50.5 And 31.5
