Answer:
2 selves.
Step-by-step explanation:
Let x represent the number of shelves having 2 cars.
Number of cars on x shelves would be \(2x\).
We have been given that 8 of the shelves each display 1 car, so number of cars displayed on 8 shelves would be \(8\times 1 =8\).
We have been given that Cameron 12 model cars to display on shelves. This means that number of cars on x shelves plus 8 cars would be equal to 12.
We can represent this information in an equation as:
\(2x+8=12\)
\(2x+8-8=12-8\)
\(2x=4\)
\(\frac{2x}{2}=\frac{4}{2}\)
\(x=2\)
Therefore, 2 shelves will display 2 cars.
