Answer:
x=-4 and y=2 Those 2 equations when graphed give a vertical line and a horizontal line that intersect at the point (-4,2)
x+4=0 and y-2=0 are the same two lines.
or if you want more complicated systems of equations, with the same solution:
x+y=-2 and x-y=-6
in standard form, that's y=-x-2 and y=x+6 Graph those two lines and they intersect at (-4,2)
Those 2 lines are with slopes of -1 and +1. Those 2 equations are a system of equations
whose solution is x=-4 and y=2.
Rotate two perpendicular lines around the point (-4,2) and you get more systems of
equations with the same solution.
They don't have to be perpendicular though. x+y=-2 and x=-4 are two lines forming
a 45 degree angle, with the same solution (-4,2)
They don't have to be linear either. Take a parabola with the vertex (-4,2) and the line x=-4.
They intersect at the point (-4,2). That parabola could be the simple y=x2 shifted up and
to the left, to y-2 = (x+4)2 or y=x2+8x+18 or it could be any one of a family of parabolas with
the same vertex.
You could have 2 circles tangent at the point (-4,2) Endless circles could have that point
as a tangent and their equations having that same solution (-4,2)
