The Sum Of Two Numbers Is 88 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 88 X - Y = 12 2X = 100 |
Let's divide 100 to 2 for the first number "X" .
X/2 = 50
First number is 50
X + Y = 88
So ;
50 + Y = 88
Y = 88 - 50
Y = 38
Second number is 38
Question & Answer
