A total of

556
tickets were sold for the school play. They were either adult tickets or student tickets. There were
56
more student tickets sold than adult tickets. How many adult tickets were sold?

Let's represent the number of adult tickets sold as "x".

Since there were 56 more student tickets sold than adult tickets, the number of student tickets sold can be represented as "x + 56".

The total number of tickets sold is the sum of adult tickets and student tickets, which is 556.

So, we can write the equation:

x + (x + 56) = 556

Now, let's solve for x.

2x + 56 = 556
2x = 556 - 56
2x = 500
x = 500/2
x = 250

Therefore, 250 adult tickets were sold.

To find the number of adult tickets sold, we need to set up an equation based on the information given. We know that the total number of tickets sold is 556 and there were 56 more student tickets sold than adult tickets.

Let's assume the number of adult tickets sold is "x". Therefore, the number of student tickets sold would be "x + 56" since there were 56 more student tickets sold.

Now we can set up the equation:
x + (x + 56) = 556

We can simplify it by combining like terms:
2x + 56 = 556

To isolate the variable, we subtract 56 from both sides:
2x = 500

Finally, we solve for x by dividing both sides by 2:
x = 250

Therefore, 250 adult tickets were sold for the school play.

a = adult tickets

a + a + 56 = 556
2a = 500
a = 250
