Answer:
Step-by-step explanation:
The question we have at hand is, in other words,
- where we have to solve for the value of
If we have to isolate here, then we would have to take the inverse of the following matrix ...
... so that it should be as follows ...
Therefore, we can conclude that the equation as to solve for " " will be the following,
- First find the 2 x 2 matrix inverse of the first portion,
=
=
=
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
,
- Simplifying this, we should get ...
... which is our solution.
