Question 550965
Here is the equation:

2x - 5 + 2x + x = 180


5x - 5 = 180


5x = 180 + 5


5x = 185


x = 185/5


x = 37


Emma sold 2(37) - 5 tickets or 69 tickets.


Jackson sold 37(2) = 74 tickets.


Nicholas sold 37 tickets.


How do we know if this is the right answer?


Let's add 37 + 74 + 69.  If the total is 180, then the answer is correct.


37 + 74 + 69 = 180
