The Sum Of Two Numbers Is 84 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 84 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 84
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 84 X - Y = 10 2X = 94 |
Let's divide 94 to 2 for the first number "X" .
X/2 = 47
First number is 47
X + Y = 84
So ;
47 + Y = 84
Y = 84 - 47
Y = 37
Second number is 37
Question & Answer
