Question 73738
You can solve by adding the 2 equations together since there is a 1/3x and a -1/3x.
{{{y=-1/3x+1}}}
+{{{y=1/3x-3}}}
----------------
{{{2y=-2}}}Now solve for y
{{{y=-1}}}
Plug this back into {{{y=-1/3x+1}}}
{{{-1=-1/3x+1}}}
{{{-2=-1/3x}}}
{{{(-2)*(-3)=x}}}
{{{x=6}}}
So the solution is (6,-1)
Check:
{{{-1=(-1/3)(6)+1}}}
{{{-1=-2+1}}}
{{{-1=-1}}}works
{{{-1=(1/3)(6)-3}}}
{{{-1=2-3}}}
{{{-1=-1}}}works
