Priya was busy studying this week and ran 7 fewer miles than last week. she ran 9 times as far as elena ran this week. elena only had time to run 4 miles this week.
how many miles did priya run last week
elena writes the equation 1/9(x﹣7) = 4 to describe the situation. she solves the equation by multiplying each side by 9 and then adding 7 to each side. how does her solution compare to the way you found priya’s miles?
