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)
----> is ok
