Final answer:
Without sufficient information regarding matrix X, the value in row 1, column 1 cannot be determined and is thus indeterminate.
Step-by-step explanation:
The value of the element in row 1, column 1 of matrix X is indeterminate from the information provided. The practice test information given does not specify the elements of matrix X. Instead, it provides details on a linear equation and a step in solving a quadratic equation which are not directly related to matrix X. Therefore, without additional data regarding the contents of matrix X, we cannot determine the element in the specified position.
The value of the element in row 1, column 1 of matrix X can be found by looking at the first element of the first row in the matrix. In this case, we can see that the answer is 4 as given in option A.
