Question 72662
{{{ -4=-2x }}}
.
Your work is correct all the way down to the above step.  All you need to do is divide
both sides of this equation by -2 to get that 2 = x. Or if you prefer you could have
multiplied both sides of the equation by -1 to get:
.
{{{4 = 2x}}}
.
and then divided both sides by +2 to get
.
{{{ 2 = x}}}
.
and this can be transposed into {{{x = 2}}} and this is the correct answer to the problem.  
.
Hopefully this explains what was bothering you.  You did all the hard steps correctly. 
Keep up the good work!
