Write an equation to represent this real world situation Andre wants to practice the piano 9 hours a week each time he practices he practices for 2/3 hour if he has already practiced 2 hours this week how many sessions X does he still need to practice to reach or surpass his goal

Let X be the number of sessions Andre still needs to practice.

Each session Andre practices for 2/3 hour.

Andre wants to practice 9 hours a week, so the total number of hours Andre needs to practice is 9.

Andre has already practiced 2 hours this week, so the number of hours he still needs to practice is 9 - 2 = 7.

Since each session is 2/3 hour, the equation can be written as:
(2/3)X = 7
