Let's look at an example of an algebra word problem. Algebra Word Problems Linda was selling tickets for the school play.

She sold 10 more adult tickets than children tickets and she sold twice as many senior tickets as children tickets. Let x represent the number of children's tickets sold. Write an expression to represent the number of adult tickets sold.
