Answer:
Step-by-step explanation:
First you will divide I-2xI on both sides that should look like this: 
        -2x/-2 = 10/-2
when you divide it your -2‘s should cancel out and you should be left with 
          -x=10/-2
when You divide 10/-2 you should get -5
          10/-2= -5
your answer should look like this then 
          -x=-5 
-5 is just one of your answers the other is 5 
 To get rid of the negative on the -X you have to didvide it by both sides
         -x/-x=-5/-x
your answer should be 
           X= 5
your final answers are 
       -5 or 5
