Question 178872
</pre><font size=4><b>
Arrange eqns:
{{{2x = 2 - y}}}, EQN 1
{{{3x + y = -1}}}, EQN 2

{{{system(-2x-y=-2,3x+y=-1)}}}--->{{{system(-2x-cross(y)=-2,3x+cross(y)=-1,x=-3)}}}
subst.{{{highlight(x=-3)}}} in EQN 2:
{{{3(-3)+y=-1}}}
{{{-9+y=-1}}}
{{{y=-1+9}}}
{{{highlight(y=8)}}}
we'll see the graph:
{{{drawing(400,400,-5,5,-10,10,grid(1),graph(400,400,-5,5,-10,10,2-2x,-1-3x),blue(circle(-3,8,.12)))}}}
Thank you,
