Perform the operation for each equation, if there is a solution

[4k -8y ] [5k+6y 2k+1]
[6z - 3x] - [2z+5x z+4]
[2k + 5a] [4k+6a 3a+2]

To perform the operation for each equation, we will subtract the second matrix from the first matrix.

Let's break down the steps for each equation:

1. [4k - 8y] - [5k + 6y 2k + 1]:
Subtract the corresponding elements of the matrices:
(4k - 5k) - (8y + 6y) = -k - 14y
(0 - 2k) - (8y + 1) = -2k - 9
The solution for this equation is (-k - 14y, -2k - 9).

2. [6z - 3x] - [2z + 5x z + 4]:
Subtract the corresponding elements of the matrices:
(6z - 2z) - (3x + 5x) = 4z - 8x
(0 - z) - (3x + 4) = -z - 3x - 4
The solution for this equation is (4z - 8x, -z - 3x - 4).

3. [2k + 5a] - [4k + 6a 3a + 2]:
Subtract the corresponding elements of the matrices:
(2k - 4k) - (5a + 6a) = -2k - 11a
(0 - 3a) - (5a + 2) = -3a - 5
The solution for this equation is (-2k - 11a, -3a - 5).

Therefore, for each equation, there is a solution represented by the respective expressions.
