The Sum Of Two Numbers Is 64 And Their Difference Is 32
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 32. Let's find the two numbers :When we add the two numbers :
X + Y = 64
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 = 64 X - Y = 32 2X = 96 |
Let's divide 96 to 2 for the first number "X" .
X/2 = 48
First number is 48
X + Y = 64
So ;
48 + Y = 64
Y = 64 - 48
Y = 16
Second number is 16
Question & Answer
