The Sum Of Two Numbers Is 80 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 80 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 80
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 80 X - Y = 8 2X = 88 |
Let's divide 88 to 2 for the first number "X" .
X/2 = 44
First number is 44
X + Y = 80
So ;
44 + Y = 80
Y = 80 - 44
Y = 36
Second number is 36
Question & Answer
The Sum Of Two Numbers Is 80 And Their Difference Is 8 : 44 And 36
