Find the equation that best represents the following word problem: In a certain freshman class, the number of girls is 83 less than twice the number of boys (b). The total number of students in that freshman class is 259. How many boys and girls are in that class? 

• b + 2b = 259 - 83 
• b + 2b – 83 = 259 
• b + 83 – 2b = 259 
• b + 2b = 259
