Question

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

Answer 1

\[X=\left[\begin{matrix}x_1 & x_2 \\ x_3 & x_4\end{matrix}\right]\]
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

Answer 2

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

Answer 3

not much more to explain

you should be able to do systems of equations if you're learning this

Answer 4

are you learning about inverses of matrices?
