The Sum Of Two Numbers Is 75 And Their Difference Is 32
The problem given says that 2 unknown numbers are given, whose sum is equal to 75 and the difference is 32. Let's find the two numbers :When we add the two numbers :
X + Y = 75
The difference of two numbers :
X - Y = 32
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 75 X - Y = 32 2X = 107 |
Let's divide 107 to 2 for the first number "X" .
X/2 = 53.5
First number is 53.5
X + Y = 75
So ;
53.5 + Y = 75
Y = 75 - 53.5
Y = 21.5
Second number is 21.5
Question & Answer
The Sum Of Two Numbers Is 75 And Their Difference Is 32 : 53.5 And 21.5
