The Sum Of Two Numbers Is 53 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 53 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 53
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 53 X - Y = 18 2X = 71 |
Let's divide 71 to 2 for the first number "X" .
X/2 = 35.5
First number is 35.5
X + Y = 53
So ;
35.5 + Y = 53
Y = 53 - 35.5
Y = 17.5
Second number is 17.5
Question & Answer
