The Sum Of Two Numbers Is 64 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 64 X - Y = 3 2X = 67 |
Let's divide 67 to 2 for the first number "X" .
X/2 = 33.5
First number is 33.5
X + Y = 64
So ;
33.5 + Y = 64
Y = 64 - 33.5
Y = 30.5
Second number is 30.5
Question & Answer
The Sum Of Two Numbers Is 64 And Their Difference Is 3 : 33.5 And 30.5
