The Sum Of Two Numbers Is 69 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 69
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 69 X - Y = 3 2X = 72 |
Let's divide 72 to 2 for the first number "X" .
X/2 = 36
First number is 36
X + Y = 69
So ;
36 + Y = 69
Y = 69 - 36
Y = 33
Second number is 33
Question & Answer
