The Sum Of Two Numbers Is 75 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 75 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 75
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 = 75 X - Y = 8 2X = 83 |
Let's divide 83 to 2 for the first number "X" .
X/2 = 41.5
First number is 41.5
X + Y = 75
So ;
41.5 + Y = 75
Y = 75 - 41.5
Y = 33.5
Second number is 33.5
Question & Answer
