The Sum Of Two Numbers Is 74 And Their Difference Is 28
The problem given says that 2 unknown numbers are given, whose sum is equal to 74 and the difference is 28. Let's find the two numbers :When we add the two numbers :
X + Y = 74
The difference of two numbers :
X - Y = 28
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 74 X - Y = 28 2X = 102 |
Let's divide 102 to 2 for the first number "X" .
X/2 = 51
First number is 51
X + Y = 74
So ;
51 + Y = 74
Y = 74 - 51
Y = 23
Second number is 23
Question & Answer
