The Sum Of Two Numbers Is 27 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 27 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 27
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 27 X - Y = 8 2X = 35 |
Let's divide 35 to 2 for the first number "X" .
X/2 = 17.5
First number is 17.5
X + Y = 27
So ;
17.5 + Y = 27
Y = 27 - 17.5
Y = 9.5
Second number is 9.5
Question & Answer
