The Sum Of Two Numbers Is 79 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 79 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 79
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 79 X - Y = 3 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 79
So ;
41 + Y = 79
Y = 79 - 41
Y = 38
Second number is 38
Question & Answer
The Sum Of Two Numbers Is 79 And Their Difference Is 3 : 41 And 38
