When an equation is having two variables with every variables in first degree such that variables are not multiplied with each other then it is called as a linear equations in two variables.

This chapter covers the following concepts-

-Pair of linear equations in two variables

-Graphical methods of solution of a pair of linear equations

-Algebraic methods of solving a pair of linear equations- substitution method, elimination method, cross multiplication method

-equations reducible to a pair of linear equations in two variables.
