You should do 40+3 to get the answer because if you look in the ones place after you add all of the equations then you would see that the first equations answer would be 7 and it only has one digit so it wouldn't even be considered in the problem if you solve the second problem you would get 43 and yes it does have more than one digit so you should look in the ones place and look for the number 3 and if you see the number 3 then you should look at the number in front of the 3 then you you should look for the number 4 and yes the number in front of the 3 is the tenths place and just to confirm your equation you should solve the other problem even if you did already find the answer so the last equation is going to equal to 34 and it will automatically be eliminated because there is no 3 in the ones place so your answer would be he second equation
