Hi friends, welcome on Maths Master, here you will learn how to solve linear equations in two variables by Equations reducible to a pair of linear equations in two variables.
We can create new variables making a proper change in the given variables. Substituting the new variables in the given non-linear equations, we can convert them in linear equations.
Also remember that the denominator of any fraction of the form m/n cannot be zero.
Let’s see example:
In the above examples the simultaneous equations obtained by transformation are solved by elimination method.
If you solve these equations by graphical method and by Cramer’s rule will you get the same answers ? Solve and check it.
