50 POINTS! I’d really like someone to help me out with the answer, I’ve been having a lot of trouble. I’d like and explanation as well and I’ll give brainliest if provided!

Answer 1

The solution to the matrix equation is x = 2.6

What is the solution?

Following the matrix as given, all the elements in the right hand side would have to be multiplied by X hence we have;

-x   4x            -8    17

6x  3x     =      21   -21

Taking the determinant of both matrices;

-3x^2 - 24x^2 = 168 - 357

-27x^2 = -189

x^2 = -189/-27

x = 2.6
