The Sum Of Two Numbers Is 58 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 58
The difference of two numbers :
X - Y = 11
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 58 X - Y = 11 2X = 69 |
Let's divide 69 to 2 for the first number "X" .
X/2 = 34.5
First number is 34.5
X + Y = 58
So ;
34.5 + Y = 58
Y = 58 - 34.5
Y = 23.5
Second number is 23.5
Question & Answer
The Sum Of Two Numbers Is 58 And Their Difference Is 11 : 34.5 And 23.5
