The Sum Of Two Numbers Is 32 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 32 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 32
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 32 X - Y = 17 2X = 49 |
Let's divide 49 to 2 for the first number "X" .
X/2 = 24.5
First number is 24.5
X + Y = 32
So ;
24.5 + Y = 32
Y = 32 - 24.5
Y = 7.5
Second number is 7.5
Question & Answer
The Sum Of Two Numbers Is 32 And Their Difference Is 17 : 24.5 And 7.5
