The Sum Of Two Numbers Is 58 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 58
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 = 58 X - Y = 17 2X = 75 |
Let's divide 75 to 2 for the first number "X" .
X/2 = 37.5
First number is 37.5
X + Y = 58
So ;
37.5 + Y = 58
Y = 58 - 37.5
Y = 20.5
Second number is 20.5
Question & Answer
The Sum Of Two Numbers Is 58 And Their Difference Is 17 : 37.5 And 20.5
