Question

Solve the matrix equation: [-7,-3
                                             2,1] X=[2,6
                                                            6,9]

anonymous · Answer

$$X=\left[\begin{matrix}x_1 & x_2 \ x_3 & x_4\end{matrix}\right]$$
using matrix multiplication
$$-7x_1-3x_3=2$$$$2x_1+x_3=6$$$$-7x_2-3x_4=6$$$$2x_2+x_4=9$$

two systems of 2 equations with 2 knowns, solve for x1,x2,x3,x4

im not sure what to do next..can u explain more

anonymous · Answer

not much more to explain

you should be able to do systems of equations if you're learning this

anonymous · Answer

are you learning about inverses of matrices?
