The Sum Of Two Numbers Is 76 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 76 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 76
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 76 X - Y = 8 2X = 84 |
Let's divide 84 to 2 for the first number "X" .
X/2 = 42
First number is 42
X + Y = 76
So ;
42 + Y = 76
Y = 76 - 42
Y = 34
Second number is 34
Question & Answer
