Hello...! :)


\: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow-9x+5= -13


\: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow- 9x = - 13 - 5


\: \: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow - 9x = - 18


\: \: \: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow \: x = ( - 18)/( - 9)


\: \: \: \: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow \: x = (18)/(9)


\: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \dashrightarrow \: x = 2

To solve we take into account that we must solve it with the law of signs in this case is:


\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - × - = +

So, we will add (13 + 5) which should give us 19 once we have done that we know that in the fraction two minus signs give a plus sign once that is done we divide 18 divided by 9 gives us two.

So the Result is 2

¿Doubts? On the comments. Greetings :D
