-30

Answer 16

yes. When you have time, you should practice doing it in your head.

you started with
-6x + 9 = -21
you add -9 to both sides
-6x+9 -9 =-21 -9

you then got
-6x + 0 = -30

on the left side -6x + 0 is just -6x
so you have

-6x = -30

divide both sides by -6
can you do that ?

Answer 17

how do you divide -6x by -6

Answer 18

plz can u plz give me this answer cuz i got many more questions

Answer 19

-6 divided by -6 is 1

\[ \frac{-6 x }{-6}= 1x= x \]

Answer 20

now do -30/-6 on the right side

Answer 21

5

Answer 22

so
-6x = -30

divide both sides by -6, and you get
x = 5

that is the answer
