Answer:
6x - 4
Step-by-step explanation:
You messed up from the start.
You added 8 + 3 which gave you 11 and you distributed 11 to 2x and 4. (wrong)
What you were supposed to do was distrubute 3 to 2x and -4 which gives you 6x-12 then you add 8 which gives you 8+6x-12
When you simplify 8+6x-12 you get 6x-4 (answer)
You can prevent this next time by following the orders of PEMDAS
P in pemdas means parenthesis which is what you should have done first.
