**Algebraic Methods Of Solving A Pair Of Linear Equations**

Sometimes, graphical method does not give an accurate answer. While reading the coordinates of a point on a graph paper, we are likely to make an error. So, we require some precise method to obtain accurate result. Algebraic methods given below yield accurate answers.

(i) Method of elimination by substitution

(ii) Method of elimination by equating the coefficients

(iii) Method of cross multiplication
