1st: add 5 to each side
2nd: divide by 2 on each side
Question is confusing but 12/15 divides to 4/5 or rounds to 1
Please ask the question in English, if you are not able to, I believe you are in the wrong language section and suggest you try something else before you get your question taken down.
First we are going to start by subtracting 3-10 and that gives us 7 so then you divide 7 by 4”3 and you get 2.3
