Answer:
An electronics company can be produce 350 transistors and 340 computer chips, they can´t produce resistors.
Step-by-step explanation:
1. We will name the variables for transistors, resistors and the computer chips.
a = Transistors
b= Resistors
c = Computer chips
2. We propose three linear equations, one for the copper, one for the zinc and one for the glass.

3. We write the matrix form as Ax=d



With this formula the solution of x is
or 
4. We will find the inverse matrix
using the formula:

a. det A
![det A=\left[\begin{array}{ccc}3&3&2\\1&2&1\\2&1&2\end{array}\right] =3*(4-1)-3*(2-2)+2*(1-4)=9-0-6=3](https://tex.z-dn.net/?f=det%20A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%263%262%5C%5C1%262%261%5C%5C2%261%262%5Cend%7Barray%7D%5Cright%5D%20%3D3%2A%284-1%29-3%2A%282-2%29%2B2%2A%281-4%29%3D9-0-6%3D3)
b. 




c.

5. As
or
, the solution of x is:



![X=\left[\begin{array}{ccc}350\\0\\340\end{array}\right]](https://tex.z-dn.net/?f=X%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D350%5C%5C0%5C%5C340%5Cend%7Barray%7D%5Cright%5D)
<u><em>Therefore:</em></u>
<u><em>a= 350 Transistors</em></u>
<u><em>b=0 Resistors</em></u>
<u><em>c=340 Computer chips</em></u>
