The Sum Of Two Numbers Is 73 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 73 X - Y = 2 2X = 75 |
Let's divide 75 to 2 for the first number "X" .
X/2 = 37.5
First number is 37.5
X + Y = 73
So ;
37.5 + Y = 73
Y = 73 - 37.5
Y = 35.5
Second number is 35.5
Question & Answer
The Sum Of Two Numbers Is 73 And Their Difference Is 2 : 37.5 And 35.5
