The Sum Of Two Numbers Is 73 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 9
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 73 X - Y = 9 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 73
So ;
41 + Y = 73
Y = 73 - 41
Y = 32
Second number is 32
Question & Answer
