The Sum Of Two Numbers Is 32 And Their Difference Is 28
The problem given says that 2 unknown numbers are given, whose sum is equal to 32 and the difference is 28. Let's find the two numbers :When we add the two numbers :
X + Y = 32
The difference of two numbers :
X - Y = 28
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 32 X - Y = 28 2X = 60 |
Let's divide 60 to 2 for the first number "X" .
X/2 = 30
First number is 30
X + Y = 32
So ;
30 + Y = 32
Y = 32 - 30
Y = 2
Second number is 2
