A boat weighs 1500 lb more than its motor and 1900 lb more than its trailer. Together the boat and motor weigh five times as much as the trailer. How much does the boat weight?
I have tried so many times for the past twenty minutes!! I can't get it!! Thank you so much.
Here is the last thing I tried:
x+1500=boat
x=trailer
x+400=motor
x+1500+x=5(x+400)
2x+1500+5x+2000
2x=5x+500
-3x=500
x=-166.666666 (It doesn't work) =(

You can put this solution on YOUR website!
B=M+1,500 OR M=B-1,500
B=T+1,900 OR T=B-1,900
B+M=5T
B+(B-1.500)=5(B-1,900)
2B-1,500=5B-9,500
5B-2B=-1,500+9,500
3B=8,000
B=8,000/3
B=2,666.67 LBS. IS THE WEIGHT OF THE BOAT.
