Atotal of 500 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was three times the number of adult tickets sold. how many adult tickets were sold?

Lets x = number adult tickets sold

       3x = number student tickets sold

Now you have:

x +3x = 500

4x = 500

x =500/4 = 125

125 adults tickets were sold.

to rewrite a literal equation you may need to divide by a number, or by a variable.

hope i .
