The Sum Of Two Numbers Is 80 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 80 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 80
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 80 X - Y = 14 2X = 94 |
Let's divide 94 to 2 for the first number "X" .
X/2 = 47
First number is 47
X + Y = 80
So ;
47 + Y = 80
Y = 80 - 47
Y = 33
Second number is 33
Question & Answer
The Sum Of Two Numbers Is 80 And Their Difference Is 14 : 47 And 33
