hmmm... we have -7625+185x and that is = to -12790
so the way to get the anwser is to get x by itself.
to do that we add 7625 to each side to nullify the -7625
that brings us to 185x=-5165
then we divide each side by 185
thaqt brings us to -28 rounded
so x=-28 rounded
if you want the decimal it is x=-27.9189189189189189
