The Sum Of Two Numbers Is 69 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 69
The difference of two numbers :
X - Y = 37
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 69 X - Y = 37 2X = 106 |
Let's divide 106 to 2 for the first number "X" .
X/2 = 53
First number is 53
X + Y = 69
So ;
53 + Y = 69
Y = 69 - 53
Y = 16
Second number is 16
Question & Answer
