Question

Anyone willing to help solve Matrices?
Solve each matrix equation
15.)
3[2 0] -2X=[-10 5]
[-1 5] [0 17]

16.)
4X+ [1 3] = [-3 11]
[-7 9] [5 -7]

Answer 1

Is the first one [6 0]
[-1 5]? well for the first part?

Answer 2

\[3 \left[\begin{matrix}2 & 0 \\ -1 & 5\end{matrix}\right]=\left[\begin{matrix}6 & 0 \\ -3 & 15\end{matrix}\right]\]

Answer 3

Ohh. . .Don't know how you got that, but ugh, thanks.

Answer 4

\[\left[\begin{matrix}6 & 0 \\ -3 & 15\end{matrix}\right]-\left[\begin{matrix}-10 & 5 \\ 0 & 17\end{matrix}\right]=2 X\]

Answer 5

\[2 X=\left[\begin{matrix}6+10 & 0-5 \\ -3-0 & 15-17\end{matrix}\right]\]

Answer 6

\[2 X=\left[\begin{matrix}16 & -5 \\ -3 & -2\end{matrix}\right]\]

Answer 7

\[X=\left[\begin{matrix}8 & -5/2 \\ -3/2 & -1\end{matrix}\right]\]

Answer 8

Thanks for your patience. <3
