Wt. of motor = X lbs.
Wt. of boat = (X+1500) lbs.
Wt. of trailer=(X+1500)-1900=X-400lbs.
X + (X+1500) = 5(X-400),
2X + 1500 = 5X - 2000,
2X - 5X = -2000 - 1500,
-3X = -3500,
X = 1167 lbs = Wt. of motor.
X+1500 = 2667 lbs = Wt. of boat.
Wt. of boat = (X+1500) lbs.
Wt. of trailer=(X+1500)-1900=X-400lbs.
X + (X+1500) = 5(X-400),
2X + 1500 = 5X - 2000,
2X - 5X = -2000 - 1500,
-3X = -3500,
X = 1167 lbs = Wt. of motor.
X+1500 = 2667 lbs = Wt. of boat.
