The Sum Of Two Numbers Is 25 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 25 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 25
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 = 25 X - Y = 8 2X = 33 |
Let's divide 33 to 2 for the first number "X" .
X/2 = 16.5
First number is 16.5
X + Y = 25
So ;
16.5 + Y = 25
Y = 25 - 16.5
Y = 8.5
Second number is 8.5
Question & Answer
