The Sum Of Two Numbers Is 69 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 69
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 69 X - Y = 5 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 69
So ;
37 + Y = 69
Y = 69 - 37
Y = 32
Second number is 32
Question & Answer
