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.
0.8 or 4/5
Both are correct, but in different form.
Your welcome.

Answer:
L Pie - $7.50
B Pie - $4.50
Step-by-step explanation:
Let's create equations with the given things:
1. Two lemon meringue pies cost $3 less than four blueberry pies.
2L - $3 = 4B
2. Three lemon meringue pies cost #9 more than three blueberry pies.
3L = $9+3B
3. Let's solve these 2 equations
1. -3(-4B+2L=-3)
2. 2(-3B+3L=9)
3. Adding these 2 equations:
12B-6L = 9 ----(1)
-6B+6L= 18 ----(2)
(1) + (2) => 6B=27
B=$4.50
4. 2L = 4(4.50) - 3
L= $7.50
