Question 446656
{{{-9x-3y =22}}}
{{{y = -3x-6 }}}

---------------------------
{{{-9x-3y =22}}}

{{{3x+y = -6 }}}



*[invoke solving_linear_system_by_elimination -9, -3, 22, 3, 1, -6]

check with a graph:

{{{y = -3x-22/3 }}}

{{{y = -3x-6 }}}

{{{ graph( 500, 500, -10, 10, -10, 10, -3x-6, -3x-22/3) }}}


as you can see from the graph, lines are parallel; so, system doesn't have a solution.
