Answer:
3 x + 10 y = 50
This is the equation which can be used to find the number of each type of weight Bob has.
Step-by-step explanation:
Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs.
Let x represents the number of 3 lb weights and y represents the number of 10 lb weights
Total weight = 50 lb
Number of 3 lb weights = x
Number of 10 lb weights = y
Equating
3 x + 10 y = 50
This is the equation which can be used to find the number of each type of weight Bob has.
