The Sum Of Two Numbers Is 73 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 73 X - Y = 10 2X = 83 |
Let's divide 83 to 2 for the first number "X" .
X/2 = 41.5
First number is 41.5
X + Y = 73
So ;
41.5 + Y = 73
Y = 73 - 41.5
Y = 31.5
Second number is 31.5
Question & Answer
The Sum Of Two Numbers Is 73 And Their Difference Is 10 : 41.5 And 31.5
