The Sum Of Two Numbers Is 84 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 84 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 84
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 = 84 X - Y = 37 2X = 121 |
Let's divide 121 to 2 for the first number "X" .
X/2 = 60.5
First number is 60.5
X + Y = 84
So ;
60.5 + Y = 84
Y = 84 - 60.5
Y = 23.5
Second number is 23.5
Question & Answer
