Let's call bicycles 'b' and unicycles 'u' Note that bicycles have 2 tires, and unicycles have 1 tire. We can make two equations: b = u + 8 2b + 1u = 46 Solving the first equation for u, we get: u = b - 8 Plug that equation into the second, and we get: 2b + (b - 8) = 46 Subtract 2b on both sides. 1(b - 8) = 46 - 2b Basically, I used b and your question used n. The correct answer is: D. 1(n - 8) = 46 - 2n .
