You can put this solution on YOUR website!
Commonly known methods to solve a linear system of equations are Substitution, Elimination, and Row-reduction, or use of matrices.


Try to simplify your second equation.
81y%2B27=162x
162x-81y=27
18x-9y=3
6x-3y=1-------------identical to the first equation of your list.

You do not really have a system of equations any more; but instead just one single linear equation in two variables.
