The Sum Of Two Numbers Is 17 And Their Difference Is 1
The problem given says that 2 unknown numbers are given, whose sum is equal to 17 and the difference is 1. Let's find the two numbers :When we add the two numbers :
X + Y = 17
The difference of two numbers :
X - Y = 1
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 17 X - Y = 1 2X = 18 |
Let's divide 18 to 2 for the first number "X" .
X/2 = 9
First number is 9
X + Y = 17
So ;
9 + Y = 17
Y = 17 - 9
Y = 8
Second number is 8
Question & Answer
