The Sum Of Two Numbers Is 90 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 90 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 90
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 90 X - Y = 2 2X = 92 |
Let's divide 92 to 2 for the first number "X" .
X/2 = 46
First number is 46
X + Y = 90
So ;
46 + Y = 90
Y = 90 - 46
Y = 44
Second number is 44
Question & Answer
The Sum Of Two Numbers Is 90 And Their Difference Is 2 : 46 And 44
