The Sum Of Two Numbers Is 82 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 82 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 82
The difference of two numbers :
X - Y = 37
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 82 X - Y = 37 2X = 119 |
Let's divide 119 to 2 for the first number "X" .
X/2 = 59.5
First number is 59.5
X + Y = 82
So ;
59.5 + Y = 82
Y = 82 - 59.5
Y = 22.5
Second number is 22.5
Question & Answer
