The Sum Of Two Numbers Is 82 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 82 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 82
The difference of two numbers :
X - Y = 26
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 82 X - Y = 26 2X = 108 |
Let's divide 108 to 2 for the first number "X" .
X/2 = 54
First number is 54
X + Y = 82
So ;
54 + Y = 82
Y = 82 - 54
Y = 28
Second number is 28
