In these lessons, we will learn what are equal matrices?
Related Topics: Operations on Matrices
Two matrices are equal if they have the same dimension or order and the corresponding elements are identical.
Matrices P and Q are equal.
Matrices A and B are not equal because their dimensions or order is different.
We can use the equality of matrices to solve for variables.
Example:
Given that the following matrices are equal, find the values of x, y and z .
Solution:
Equate the corresponding elements and solve for the variables.
x + 3 = 6
x = 3
y = −1
z −3 = 4
z = 7
