Fifteen more than twice the hours carla worked last week is the same as three times the hours she worked this week decreased by 15.she worked the same number of hours each week.how many hours did she work each week.
Let h = the hours worked in a week....and we have
2h + 15 = 3h - 15 add 15 to both sides, subtract 2h from both sides
30 = h
She worked 30 hours each week
thanks
