\"\"

\

The system of equations are \"\" and \"\".

\

Solve the equation.

\

\"\"                               (First equation)

\

\"\"            (Subtract \"\" from each side)

\

\"\"                            (Apply additive inverse property: \"\")

\

\"\"                       (Divide each side by \"\")

\

\"\"                                (Cancel common terms)

\

Substitution method:

\

\"\"                             (Second equation)

\

\"\"                (Substitute \"\")

\

\"\"                     (Distributive property: \"\")

\

\"\"                                  (Apply additive inverse property: \"\")

\

Because \"\" is true because both represent same line equation.

\

Hence the system has infinitely many solutions.
