The Sum Of Two Numbers Is 52 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 52 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 52
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 52 X - Y = 10 2X = 62 |
Let's divide 62 to 2 for the first number "X" .
X/2 = 31
First number is 31
X + Y = 52
So ;
31 + Y = 52
Y = 52 - 31
Y = 21
Second number is 21
Question & Answer
