The Sum Of Two Numbers Is 16 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 16 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 16
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 = 16 X - Y = 2 2X = 18 |
Let's divide 18 to 2 for the first number "X" .
X/2 = 9
First number is 9
X + Y = 16
So ;
9 + Y = 16
Y = 16 - 9
Y = 7
Second number is 7
Question & Answer
