Answer:
x^2 - 12x = -27
Step-by-step explanation:
Here, we want to isolate the constant for the polynomial 
To do this, we start by setting the expression to zero
Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value 
Mathematically, we have this as;
x^2 - 12x + 27 = 0
x^2 - 12x = -27
 
        
             
        
        
        
Answer: The price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
Step-by-step explanation:
Let the price of the system at the ultra electronics be u
Let the price of the system at extreme electronics be e
According to question, we have 

Now, using the substitution method, we will solve the above system of equations.

Now, put the value of u in the first equation :

Now, we put the value of u in the equation which is given by:

Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
