Answer you chosen in the option is correct!
Step-by-step explanation:
Here we can see that Remmi got x =3y -2
if we need to match it from given options we can take 3 as common factor from the right side ,Since we dont have 3 common in second term but using common number of property of numbers we can pull 3 from both terms because of which 3 is now in denominator of second term which is 2/3
therefore equation becomes as third option so answer chosen by you is correct
