The Sum Of Two Numbers Is 82 And Their Difference Is 22
The problem given says that 2 unknown numbers are given, whose sum is equal to 82 and the difference is 22. Let's find the two numbers :When we add the two numbers :
X + Y = 82
The difference of two numbers :
X - Y = 22
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 82 X - Y = 22 2X = 104 |
Let's divide 104 to 2 for the first number "X" .
X/2 = 52
First number is 52
X + Y = 82
So ;
52 + Y = 82
Y = 82 - 52
Y = 30
Second number is 30
Question & Answer
The Sum Of Two Numbers Is 82 And Their Difference Is 22 : 52 And 30
