x= -4

-3x=12

divide x by -3 and do the same on the other side

12÷(-3)= -4

hence, x= -4

if you want to check if something is right, substitute your answer into the question

hope this helped

Answer:

x = -4

Explanation:


- 3x = 12

Lets divide both the sides by -3.


= > ( - 3x)/( - 3) = (12)/( - 3)


= > x = - 4
