The Sum Of Two Numbers Is 73 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 11
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 73 X - Y = 11 2X = 84 |
Let's divide 84 to 2 for the first number "X" .
X/2 = 42
First number is 42
X + Y = 73
So ;
42 + Y = 73
Y = 73 - 42
Y = 31
Second number is 31
Question & Answer
The Sum Of Two Numbers Is 73 And Their Difference Is 11 : 42 And 31
