The Sum Of Two Numbers Is 38 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 38 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 38
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 = 38 X - Y = 5 2X = 43 |
Let's divide 43 to 2 for the first number "X" .
X/2 = 21.5
First number is 21.5
X + Y = 38
So ;
21.5 + Y = 38
Y = 38 - 21.5
Y = 16.5
Second number is 16.5
Question & Answer
The Sum Of Two Numbers Is 38 And Their Difference Is 5 : 21.5 And 16.5
