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

$450=2x+50$

Solve

solve for x

$450=2x+50$

$2x=450-50\\2x=400\\x=\$200$

Check

substitute the value of x in the equation

$450=2(200)+50$

$450=450$ ----> is ok
