First you need to make those numbers into an equation. So you will have 4x+4=48. First you have to get the 4 on the other side so you do the opposite of the symbol and subtract 4 from 48 to get 44. So now you have 4x=48. Now you do the opposite og multiplication so you divide 44 by 4 and you get 11. Hope this helped :) I would appreciate it if you made this brainiest answer
