roberta sold fifty tickets for the school play. Roberta sold ten more student tickets than adult tickets. How many tickets did roberta sell?

She sold 50 tickets. You already said that.

X-Adult tickets,

(x + 10) Student tickets.

x + (x + 10) = 50 tickets,
2x + 10 = 50,
2x = 50 - 10,
2x = 40,
x = 2o.

(x + 10) = 20 + 10 = 30.

To find the number of tickets Roberta sold, we'll set up an equation based on the given information.

Let's assume the number of adult tickets Roberta sold is x.
Then the number of student tickets she sold would be x + 10, as she sold ten more student tickets than adult tickets.

So, we have the equation: x + (x + 10) = 50

Simplifying, we combine like terms: 2x + 10 = 50

Next, we'll subtract 10 from both sides to isolate the variable: 2x = 40

Finally, to solve for x, we divide both sides by 2: x = 20

So, Roberta sold 20 adult tickets (x) and 20 + 10 = 30 student tickets (x + 10). In total, Roberta sold 20 + 30 = 50 tickets.
