Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
the solution will be where the two lines intersect
the standard form for a line is y = mx + b where m is slope and b is y intercept
put both equations in standard form
we begin with
-3x-y = 7
2x + 3y = -7
1) -y = 3x +7
y = -3x -7
2) 3y = -2x -7
y = -2x/3 -7/3
now our two equations are
y = -3x -7
y = -2x/3 -7/3
graph of the equations is
the two lines intersect at point (-2, -1)
