The Sum Of Two Numbers Is 77 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 77 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 77
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 77 X - Y = 5 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 77
So ;
41 + Y = 77
Y = 77 - 41
Y = 36
Second number is 36
Question & Answer
