The Sum Of Two Numbers Is 32 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 32 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 32
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 32 X - Y = 18 2X = 50 |
Let's divide 50 to 2 for the first number "X" .
X/2 = 25
First number is 25
X + Y = 32
So ;
25 + Y = 32
Y = 32 - 25
Y = 7
Second number is 7
Question & Answer
