The Sum Of Two Numbers Is 55 And Their Difference Is 1

The problem given says that 2 unknown numbers are given, whose sum is equal to 55 and the difference is 1. Let's find the two numbers :

When we add the two numbers :
X + Y = 55

The difference of two numbers :
X - Y = 1

Solution :

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

X + Y = 55
X - Y = 1

2X = 56

Let's divide 56 to 2 for the first number "X" .

X/2 = 28

First number is 28

X + Y = 55
So ;
28 + Y = 55
Y = 55 - 28
Y = 27

Second number is 27
