The Sum Of Two Numbers Is 53 And Their Difference Is 21
The problem given says that 2 unknown numbers are given, whose sum is equal to 53 and the difference is 21. Let's find the two numbers :When we add the two numbers :
X + Y = 53
The difference of two numbers :
X - Y = 21
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 53 X - Y = 21 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 53
So ;
37 + Y = 53
Y = 53 - 37
Y = 16
Second number is 16
Question & Answer
