The Sum Of Two Numbers Is 75 And Their Difference Is 13
The problem given says that 2 unknown numbers are given, whose sum is equal to 75 and the difference is 13. Let's find the two numbers :When we add the two numbers :
X + Y = 75
The difference of two numbers :
X - Y = 13
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 75 X - Y = 13 2X = 88 |
Let's divide 88 to 2 for the first number "X" .
X/2 = 44
First number is 44
X + Y = 75
So ;
44 + Y = 75
Y = 75 - 44
Y = 31
Second number is 31
Question & Answer
