The Sum Of Two Numbers Is 86 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 86 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 86
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 = 86 X - Y = 2 2X = 88 |
Let's divide 88 to 2 for the first number "X" .
X/2 = 44
First number is 44
X + Y = 86
So ;
44 + Y = 86
Y = 86 - 44
Y = 42
Second number is 42
Question & Answer
The Sum Of Two Numbers Is 86 And Their Difference Is 2 : 44 And 42
