The Sum Of Two Numbers Is 27 And Their Difference Is 16
The problem given says that 2 unknown numbers are given, whose sum is equal to 27 and the difference is 16. Let's find the two numbers :When we add the two numbers :
X + Y = 27
The difference of two numbers :
X - Y = 16
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 27 X - Y = 16 2X = 43 |
Let's divide 43 to 2 for the first number "X" .
X/2 = 21.5
First number is 21.5
X + Y = 27
So ;
21.5 + Y = 27
Y = 27 - 21.5
Y = 5.5
Second number is 5.5
Question & Answer
The Sum Of Two Numbers Is 27 And Their Difference Is 16 : 21.5 And 5.5
