You
can
solve
a
system
of
linear
equations
____________________
and
____________________
.
To
solve
a
system
of
equations
means
to
determine
if
the
system
has
____________________
,
____________________
or
____________________
many
solutions
,
and
to
find
the
solution
(
s
)
if
they
exist
.
The
two
algebraic
methods
are
:
____________________
and
____________________
.
There
are
three
things
that
can
happen
when
we
graph
two
lines
:
-
1
solution
:
this
is
the
most
common
situation
and
it
involves
lines
that
____________________
exactly
in
one
point
.
-
No
solution
:
this
only
happens
when
the
lines
are
____________________
.
-
Infinite
solutions
:
this
is
the
rarest
case
and
only
occurs
when
you
have
the
____________________
line
.
