The Sum Of Two Numbers Is 85 And Their Difference Is 24
The problem given says that 2 unknown numbers are given, whose sum is equal to 85 and the difference is 24. Let's find the two numbers :When we add the two numbers :
X + Y = 85
The difference of two numbers :
X - Y = 24
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 85 X - Y = 24 2X = 109 |
Let's divide 109 to 2 for the first number "X" .
X/2 = 54.5
First number is 54.5
X + Y = 85
So ;
54.5 + Y = 85
Y = 85 - 54.5
Y = 30.5
Second number is 30.5
Question & Answer
The Sum Of Two Numbers Is 85 And Their Difference Is 24 : 54.5 And 30.5
