The Sum Of Two Numbers Is 34 And Their Difference Is 15
The problem given says that 2 unknown numbers are given, whose sum is equal to 34 and the difference is 15. Let's find the two numbers :When we add the two numbers :
X + Y = 34
The difference of two numbers :
X - Y = 15
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 34 X - Y = 15 2X = 49 |
Let's divide 49 to 2 for the first number "X" .
X/2 = 24.5
First number is 24.5
X + Y = 34
So ;
24.5 + Y = 34
Y = 34 - 24.5
Y = 9.5
Second number is 9.5
Question & Answer
The Sum Of Two Numbers Is 34 And Their Difference Is 15 : 24.5 And 9.5
