The Sum Of Two Numbers Is 74 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 74 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 74
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 = 74 X - Y = 8 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 74
So ;
41 + Y = 74
Y = 74 - 41
Y = 33
Second number is 33
Question & Answer
The Sum Of Two Numbers Is 74 And Their Difference Is 8 : 41 And 33
