Dennis_Churaev [7]

The difference between two numbers are 3 and numbers are x and y so the equation is x-y=3

How to find the equation and what is the equation ?

equation, statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of mathematics has been driven by attempts to find answers to those questions in a systematic way.

if the difference of two numbers are 3

And one number is x and another is y

So we write the equation with operation of subtraction

x-y=3
