The Sum Of Two Numbers Is 33 And Their Difference Is 4

The problem given says that 2 unknown numbers are given, whose sum is equal to 33 and the difference is 4. Let's find the two numbers :

When we add the two numbers :
X + Y = 33

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 = 33
X - Y = 4

2X = 37

Let's divide 37 to 2 for the first number "X" .

X/2 = 18.5

First number is 18.5

X + Y = 33
So ;
18.5 + Y = 33
Y = 33 - 18.5
Y = 14.5

Second number is 14.5

Question & Answer
The Sum Of Two Numbers Is 33 And Their Difference Is 4 : 18.5 And 14.5
