I have a word problem that is from a worksheet that I do not understand how to write in order to solve. Could someone show me how this problem should be written. Thank you.
Four more than the quotient of a number and 3 is at least that number. A boat weighs 1500 lb more than its motor and 1900 lb more than its trailer. Together the boat and motor weight five times a much as the trailer. How much does the boat weigh?

thank you! I have tried about 12 different equations!
