The Sum Of Two Numbers Is 54 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 54 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 54
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 = 54 X - Y = 11 2X = 65 |
Let's divide 65 to 2 for the first number "X" .
X/2 = 32.5
First number is 32.5
X + Y = 54
So ;
32.5 + Y = 54
Y = 54 - 32.5
Y = 21.5
Second number is 21.5
Question & Answer
The Sum Of Two Numbers Is 54 And Their Difference Is 11 : 32.5 And 21.5
