Answer 4

Or are you unsure the best way to start?

Answer 5

Unsure, I'm thinking to divide and multiply but I dont know what to do so yeah.. im unsure.

Answer 6

Its best to get just the x's on one side before you start dividing and things. I would add 2 to both sides first

Answer 7

4x = -8

what do you think from here?

Answer 8

Answer 9

Division?

Answer 10

yeah! so if you divide both sides by 4 what do you get?

Answer 11

we know on the left side you get just x, that was the point of dividing the 4 away. What about on the right side?

Answer 12

we know that the answer has to have a negative in it eliminating two choices
