The Sum Of Two Numbers Is 74 And Their Difference Is 30
The problem given says that 2 unknown numbers are given, whose sum is equal to 74 and the difference is 30. Let's find the two numbers :When we add the two numbers :
X + Y = 74
The difference of two numbers :
X - Y = 30
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 74 X - Y = 30 2X = 104 |
Let's divide 104 to 2 for the first number "X" .
X/2 = 52
First number is 52
X + Y = 74
So ;
52 + Y = 74
Y = 74 - 52
Y = 22
Second number is 22
Question & Answer
