Marcus and his friend dean are selling tickets for their schools annual fun run. Between them they sell 120 tickets. Marcus sold 16 more tickets than dean. Write an equation

Let x be the number of tickets sold by Dean.

Then Marcus sold x+16 tickets.
Together they sold x + (x+16) = 2x + 16 tickets.
Since they sold 120 tickets in total, we can write:
2x + 16 = 120
Simplifying this equation by subtracting 16 from both sides, we get:
2x = 104
Dividing both sides by 2, we get:
x = 52
Therefore, Dean sold 52 tickets and Marcus sold 52+16 = 68 tickets.

Let's assume the number of tickets Dean sold is "x".

Since Marcus sold 16 more tickets than Dean, the number of tickets Marcus sold can be represented as "x + 16".

According to the information given, the total number of tickets sold by both Marcus and Dean is 120. Therefore, the equation can be written as:

x + (x + 16) = 120
