The Sum Of Two Numbers Is 65 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 65 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 65
The difference of two numbers :
X - Y = 11
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 65 X - Y = 11 2X = 76 |
Let's divide 76 to 2 for the first number "X" .
X/2 = 38
First number is 38
X + Y = 65
So ;
38 + Y = 65
Y = 65 - 38
Y = 27
Second number is 27
Question & Answer
