Answer 2

Answer:

A pair of linear equation in two variables could be solved by Three methods.

1. Substitution method: In this method , the value of one variable obtained in one equation is substituted in the other.
2. Elimination method: In this method , one equation's variable is equalised with the other equation's same variable to eliminate it and obtain the value of other variable.
3. Cross-multiplication method: In this method , the values of all variables is substituted in an equation in order to obtain the values of the variables.
