Respuesta :
I think that your answer would be 57 cause you just plug it in so you would take 12+43+2 and it would be 57.
if x is 12 so the question is x+42+2=? so the answer is that where x is 12 so go to the back and check where x is,x+42+2=58 because x is 12 look forward 12+42+2=58 that is the answer.
