The Sum Of Two Numbers Is 88 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 88 X - Y = 10 2X = 98 |
Let's divide 98 to 2 for the first number "X" .
X/2 = 49
First number is 49
X + Y = 88
So ;
49 + Y = 88
Y = 88 - 49
Y = 39
Second number is 39
Question & Answer
