The Sum Of Two Numbers Is 24 And Their Difference Is 13
The problem given says that 2 unknown numbers are given, whose sum is equal to 24 and the difference is 13. Let's find the two numbers :When we add the two numbers :
X + Y = 24
The difference of two numbers :
X - Y = 13
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 24 X - Y = 13 2X = 37 |
Let's divide 37 to 2 for the first number "X" .
X/2 = 18.5
First number is 18.5
X + Y = 24
So ;
18.5 + Y = 24
Y = 24 - 18.5
Y = 5.5
Second number is 5.5
Question & Answer
