The Sum Of Two Numbers Is 39 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 39 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 39
The difference of two numbers :
X - Y = 29
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 39 X - Y = 29 2X = 68 |
Let's divide 68 to 2 for the first number "X" .
X/2 = 34
First number is 34
X + Y = 39
So ;
34 + Y = 39
Y = 39 - 34
Y = 5
Second number is 5
