The Sum Of Two Numbers Is 34 And Their Difference Is 4

The problem given says that 2 unknown numbers are given, whose sum is equal to 34 and the difference is 4. Let's find the two numbers :

When we add the two numbers :
X + Y = 34

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 = 34
X - Y = 4

2X = 38

Let's divide 38 to 2 for the first number "X" .

X/2 = 19

First number is 19

X + Y = 34
So ;
19 + Y = 34
Y = 34 - 19
Y = 15

Second number is 15
