Question 10253
There are two things that need to be "undone" in this problem, and you can undo them in either order.  It doesn't matter.  I recommend that you begin by undoing the +5 subtracting 5 from each side.


{{{x/(-4) + 5 = 1}}}

{{{x/(-4) + 5 - 5= 1 - 5}}}
{{{x/(-4) = -4 }}}


Now, multiply both sides of the equation by -4:
{{{(-4)* (x/(-4) ) = (-4)*(-4)}}}

{{{x=16}}}


Check:  {{{(16)/(-4) + 5 = 1}}}
{{{-4 + 5 = 1}}}  
It checks.
