Step-by-step explanation:

you want to calculate what you have on the x side first so

-8=-5+x+9.          (-5+9=4)

-8=4+x

when you get to this step you want to move the 4 to the other side so it becomes (when a number is moved to the other side of the equation it becomes its opposite so if its a negative it becomes a positive)

-8-4=x

therefore x= -12
