Respuesta :
A. subtract 12 from both sides because that is the one step solution and gets x isolated
The first step in solving x +12 < 40 is A. subtract 12 from both sides.
To solve this equation, you first have to isolate the variable, x. To do this, you must subtract 12 from both of the equation. The solution will ultimately be x < 28.
Hope this helps! :)
