First, you distribute 2 among 2x and -4. This leaves you with 4x - 8 = 11 because when you distribute, you multiply both numbers inside the parenthesis by the number outside of it. Then, you need to eradicate the 8 on the left of the equal sign, so you add 8 to -8 to make it 0, and add 8 to 11 to make it 19. This leaves you with 4x = 19. Finally, you must divide 4x and 19 by 4, leaving you with x = 4.75 or 4¾.
I get why you feel like that online school can really drain you but you’ve got this. And yeah there’s going to be bumps on the way to get your encouragement but you’re going to get there but I really recommend talking to someone you know about this unless you don’t feel comfortable with that. You’ll do great just try to not give up try little by little and it’ll end up coming to you.
