Hi, the answer is 180, because 60 *3 = 180
Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
The number you would subtract on both sides would be 12... but this in and of itself is not the first step. the way you would solve this is by:
combine like terms. x + 12=20
then, subtract 12 from both sides to get variable alone.
you will end up with a final answer of x=8
