Sam has a total of 17 bikes, unicycles, and skateboards. A bike has 2 wheels, a skateboard has 4 wheels, a unicycle has one wheel and she has a total of 42 wheels. There are just as many bikes as unicycles and skateboards together. Which system models this scenario?

B + U + S = 42

2B + U + 4S = 17

B = U + S

B + U + S = 17

2B + U + 4S = 42

B = U + S

B + U + S = 17

2B + U + 4S = 42

B = U*S
