Answer:
475 transistors, 25 resistors and 50 computer chips can be produced.
Step-by-step explanation:
Let us consider, p = Number of transistors.
q = Number of resistors.
r = Number of computer chips.
The following three linear equations according to question,
The matrix form of any system, Ax = B
Where, A = Coefficient matrix
B = Constant vector
x = Variable vector
The inverse matrix, can be found by using the following formula,
Where, det A = Determinant of matrix A.
= Matrix of cofactors of A
Now, applying this formula to find ;
Here, , thus the matrix is invertible.
So, p = 475, q = 25, r = 50.
