The Sum Of Two Numbers Is 67 And Their Difference Is 36
The problem given says that 2 unknown numbers are given, whose sum is equal to 67 and the difference is 36. Let's find the two numbers :When we add the two numbers :
X + Y = 67
The difference of two numbers :
X - Y = 36
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 67 X - Y = 36 2X = 103 |
Let's divide 103 to 2 for the first number "X" .
X/2 = 51.5
First number is 51.5
X + Y = 67
So ;
51.5 + Y = 67
Y = 67 - 51.5
Y = 15.5
Second number is 15.5
Question & Answer
