There wouldn’t be a complete full answer it would be an expression unless u forgot to multiply the 6 by something :/ but otherwise the expression would be 24+24x because u have to simply everything to get 4(12-6+6x)
Then once you distribute the 4 to every number inside the parenthesis you should get
48-24+24x then just subtract the 48 from 24 to get 24+24x. Hope this helped :)
