The Sum Of Two Numbers Is 58 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 58
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 58 X - Y = 5 2X = 63 |
Let's divide 63 to 2 for the first number "X" .
X/2 = 31.5
First number is 31.5
X + Y = 58
So ;
31.5 + Y = 58
Y = 58 - 31.5
Y = 26.5
Second number is 26.5
Question & Answer
The Sum Of Two Numbers Is 58 And Their Difference Is 5 : 31.5 And 26.5
