The Sum Of Two Numbers Is 49 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 49 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 49
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 49 X - Y = 3 2X = 52 |
Let's divide 52 to 2 for the first number "X" .
X/2 = 26
First number is 26
X + Y = 49
So ;
26 + Y = 49
Y = 49 - 26
Y = 23
Second number is 23
Question & Answer
