Question

find inverse of matrix

​

Answer 1

Answer:

To find the inverse matrix, augment it with the identity matrix and perform row operations trying to make the identity matrix to the left. Then to the right will be the inverse matrix. Divide row 1 by 2: R1=R12. Subtract row 1 from row 2: R2=R2−R1.

Step-by-step explanation:

The inverse of a matrix A is a matrix that, when multiplied by A results in the identity. ... When working with numbers such as 3 or –5, there is a number called the multiplicative inverse that you can multiply each of these by to get the identity 1. In the case of 3, that inverse is 1/3, and in the case of –5, it is –1/5.
