What is matrix X if 0.5X=A? Matrix A=[6 -12 4 6].

vladimir1956 [14]

Answer:

See attachment

Step-by-step explanation:

The given matrix equation is:

$0.5X = A.$

To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:

$2 \times 0.5X =2 \times A$

This simplifies to;

$X = 2A$

By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
