Which matrix equation can be used to solve the system?

Option A:

Solution:

Given system of equations are

We can write this equation in matrix form.

Isolate the variables in the equation.

Where

This is in the form of AX = B.

– – – (1)

Let us first calculate inverse of A.

Substitute this in (2), we get

Hence option A is the correct answer.

a=r

d=q

c=p

b=s

hope this !

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
