# ## NCERT Solutions Chapter 04: Linear equation in two variables

In earlier classes, you have studied linear equations in one variable. Can you write down a linear equation in one variable? You may say that x+1=0, x+{tex}\sqrt 2 {/tex}=0 and {tex}\sqrt 2 y + \sqrt 3 - 0{/tex} are examples of linear equations in one variable. You also know that such equations have a unique (i.e., one and only one) solution. You may also remember how to represent the solution on a number line. In this chapter, the knowledge of linear equations in one variable shall be recalled and extended to that of two variables. You will be considered questions like: Does a linear equation in two variables have a solution? If yes, is it unique? What does the solution look like on the Cartesian plane? You shall also use the concepts you studied in Chapter 3 to answer these questions.
