4 x 3 = 12
12 would be the answer
I would say 110 becuz if u add all of those together u would get 100 then u find a number that will get you to 210 which would be 110 then u get 210 ..hope this helps sorry if not
So what you need to start with is taking the x from both sides as adding 12 to them. Then, you move the 27 over 4 decimals.
10 × 2 tens = 20 tens = 200
