The Sum Of Two Numbers Is 30 And Their Difference Is 2

The problem given says that 2 unknown numbers are given, whose sum is equal to 30 and the difference is 2. Let's find the two numbers :

When we add the two numbers :
X + Y = 30

The difference of two numbers :
X - Y = 2

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 30
X - Y = 2

2X = 32

Let's divide 32 to 2 for the first number "X" .

X/2 = 16

First number is 16

X + Y = 30
So ;
16 + Y = 30
Y = 30 - 16
Y = 14

Second number is 14
