Find
an
ordered
pair
(x,
y)
that
is
a
solution
to
the
equation.
x—2y=8

EXPLANATION

ELENIGIVITEES]
There
are
infinitely
many
ordered
pairs
(x
,
y)
that are
solutions
to
x
—2y=8§.
O
To
find
one,
we
can
choose
a
value
for
one
of
the
variables and
solve
for
the
other
variable.
For
example,
in
our
problem,
we'll
lety=04
Om
Then
we'll
solve
for
x.
x2(0)
=8
=)
x=8
So,
when
y=0,
we
have
x=8.
In
other
words,
the
pair
(x,
y)
=(8,
0)
is
a
solution
to
the
equation
x—2y=8.

ANSWER
