Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is  then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

Answer:
Brand X has to mix 8.4 oz of brand A mixed nuts which contain 35% peanuts and 12.6 oz of brand B mixed nuts which contain 25%, to obtain 21 oz. Bags of mixed nuts that contain 29% peanuts.
Step-by-step explanation:
Hi
We define
 , wich means Brand A has 1 oz containing 35% peanuts.
, wich means Brand A has 1 oz containing 35% peanuts.
 , wich means Brand b has 1 oz containing 25% peanuts.
, wich means Brand b has 1 oz containing 25% peanuts.
So we can build an equiation system
(1) 
(2) , after fixing it a little
, after fixing it a little
(2)
As we can use any method to solve the system, I used a calculator wich thrown the following results  and
 and  .
