Unless your "everyday life" involves work in some area of engineering, you won't use matrices in your everyday life.
The matrices must have the same dimensions.
Only square matrices have a determinant
There are no matrices in the question!
I do not. I f*cking hate matrices. I multiply sheep.
Which one of those matrices is more comfortable to sleep on?
Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.

Unless your "everyday life" involves work in some area of engineering, you won't use matrices in your everyday life.
Only square matrices have inverses.
The question contains expressions, not equations. It is not possible to solve linear expressions - whether you use matrices or not.
Matrices can't be "computed" as such; only operations like multiplication, transpose, addition, subtraction, etc., can be done. What can be computed are determinants. If you want to write a program that does operations such as these on matrices, I suggest using a two-dimensional array to store the values in the matrices, and use for-loops to iterate through the values.
While matrixes is not wrong, the proper spelling is matrices. Purists will frown upon the former, and will not go down well with English teachers/markers
how is matrices is applicable in our life?
The singular form of matrices is matrix.
The matrices must have the same dimensions.
