The Sum Of Two Numbers Is 50 And Their Difference Is 28
The problem given says that 2 unknown numbers are given, whose sum is equal to 50 and the difference is 28. Let's find the two numbers :When we add the two numbers :
X + Y = 50
The difference of two numbers :
X - Y = 28
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 50 X - Y = 28 2X = 78 |
Let's divide 78 to 2 for the first number "X" .
X/2 = 39
First number is 39
X + Y = 50
So ;
39 + Y = 50
Y = 50 - 39
Y = 11
Second number is 11
Question & Answer
