Step-by-step explanation:
Given
![8x](https://tex.z-dn.net/?f=8x)
Required:
Solve for ![x = 0,1,2,3](https://tex.z-dn.net/?f=x%20%3D%200%2C1%2C2%2C3)
For x = 0
![8x = 8 * 0](https://tex.z-dn.net/?f=8x%20%3D%208%20%2A%200)
![8x = 0](https://tex.z-dn.net/?f=8x%20%3D%200)
For x = 1
![8x = 8 *1](https://tex.z-dn.net/?f=8x%20%3D%208%20%2A1)
![8x = 8](https://tex.z-dn.net/?f=8x%20%3D%208)
For x= 2
![8x = 8 * 2](https://tex.z-dn.net/?f=8x%20%3D%208%20%2A%202)
![8x = 16](https://tex.z-dn.net/?f=8x%20%3D%2016)
For x = 3
![8x = 8 *3](https://tex.z-dn.net/?f=8x%20%3D%208%20%2A3)
![8x = 24](https://tex.z-dn.net/?f=8x%20%3D%2024)
Hence, the results are:
![\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ 8x & {0} & {8} & {16} & {24} \ \end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccccc%7Dx%20%26%20%7B0%7D%20%26%20%7B1%7D%20%26%20%7B2%7D%20%26%20%7B3%7D%20%5C%20%5C%5C%208x%20%26%20%7B0%7D%20%26%20%7B8%7D%20%26%20%7B16%7D%20%26%20%7B24%7D%20%5C%20%5Cend%7Barray%7D)

Answer:
see the procedure
Step-by-step explanation:
Identify
Let
x ---> the cost of the Xbox one at Walmart
Strategy
we know that
The cost of the Xbox one at Walmart multiplied by 2 plus $50 must be equal to $450
Set up
The algebraic expression that represent this situation is
![450=2x+50](https://tex.z-dn.net/?f=450%3D2x%2B50)
Solve
solve for x
![450=2x+50](https://tex.z-dn.net/?f=450%3D2x%2B50)
![2x=450-50\\2x=400\\x=\$200](https://tex.z-dn.net/?f=2x%3D450-50%5C%5C2x%3D400%5C%5Cx%3D%5C%24200)
Check
substitute the value of x in the equation
![450=2(200)+50](https://tex.z-dn.net/?f=450%3D2%28200%29%2B50)
