The Sum Of Two Numbers Is 82 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 82 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 82
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 = 82 X - Y = 8 2X = 90 |
Let's divide 90 to 2 for the first number "X" .
X/2 = 45
First number is 45
X + Y = 82
So ;
45 + Y = 82
Y = 82 - 45
Y = 37
Second number is 37
Question & Answer
