The Sum Of Two Numbers Is 58 And Their Difference Is 4
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 4. Let's find the two numbers :When we add the two numbers :
X + Y = 58
The difference of two numbers :
X - Y = 4
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 58 X - Y = 4 2X = 62 |
Let's divide 62 to 2 for the first number "X" .
X/2 = 31
First number is 31
X + Y = 58
So ;
31 + Y = 58
Y = 58 - 31
Y = 27
Second number is 27
Question & Answer
