The Sum Of Two Numbers Is 64 And Their Difference Is 33
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 33. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 33
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 64 X - Y = 33 2X = 97 |
Let's divide 97 to 2 for the first number "X" .
X/2 = 48.5
First number is 48.5
X + Y = 64
So ;
48.5 + Y = 64
Y = 64 - 48.5
Y = 15.5
Second number is 15.5
Question & Answer
The Sum Of Two Numbers Is 64 And Their Difference Is 33 : 48.5 And 15.5
