The Sum Of Two Numbers Is 89 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 89 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 89
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 89 X - Y = 5 2X = 94 |
Let's divide 94 to 2 for the first number "X" .
X/2 = 47
First number is 47
X + Y = 89
So ;
47 + Y = 89
Y = 89 - 47
Y = 42
Second number is 42
Question & Answer
