QuestionSolve the matrix equation 2X+A=B2 X+A=B for XX if A=[380959]A=\left[\begin{array}{rr}3 & -8 \\ 0 & 9 \\ -5 & 9\end{array}\right] and B=[188433]B=\left[\begin{array}{rr}-1 & -8 \\ 8 & 4 \\ -3 & 3\end{array}\right]. X=X= \square (Simplify your answer.)

Studdy Solution
Divide each element of the resulting matrix by 2 to solve for X X :
X=12[408526] X = \frac{1}{2} \begin{bmatrix} -4 & 0 \\ 8 & -5 \\ 2 & -6 \end{bmatrix}
X=[2045213] X = \begin{bmatrix} -2 & 0 \\ 4 & -\frac{5}{2} \\ 1 & -3 \end{bmatrix}
The solution for X X is:
X=[2045213] X = \begin{bmatrix} -2 & 0 \\ 4 & -\frac{5}{2} \\ 1 & -3 \end{bmatrix}
