You can
put this solution on YOUR website!Using order of operations, we expand the equation to
, which simplifies to
. Adding 6 to both sides produces
, which simplifies to
. Now subtract
from both sides:
, which simplifies to
. To check it, substitute 9 in for x in the original equation:
, which simplifies to
and that further reduces to
, and finally
, which is a true statement. Because that is a true statement, that means our answer of
is correct.
