Mathcasts-Matrices

Below you will find a mathcast for section 3.1 and finding missing values of x and y from two matrices that are equal. In order for two matrices to be **equal**, they must have the same dimensions and same entries.

__**Example A**__ Are the following matrices equal?



Solution ﻿- both matrices have the same dimension, however each corresponding entry is not the same. the matrices are not equal.



__**Example B**__ Find the value of x and y. You can view the screen cast to see the solutions. media type="custom" key="10678238"
