The Sum Of Two Numbers Is 39 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 39 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 39
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 = 39 X - Y = 11 2X = 50 |
Let's divide 50 to 2 for the first number "X" .
X/2 = 25
First number is 25
X + Y = 39
So ;
25 + Y = 39
Y = 39 - 25
Y = 14
Second number is 14
Question & Answer
