Answer 1

@amistre64 Do you know how to do these?

Answer 2

of course i do

Answer 3

this isnt matrix multiplication, its scalar multiplicaton and matrix addition

Answer 4

multiply everything in A by -5 to get -5A

multiply everything in B by 4 to get 4B

then just combine 'like' elements from each matrix

Answer 5

for example, both top left elements combine as:

-5(6) + 4(-5) to get the top left elements of the solution

the top right element is the same concept .... combine the top left elements of the matrixes as:

-5(1) + 4(-1) to get the top right element of the solution

Answer 6

as is, the middle left element will better define the solution since there are 2 options with a correct top row
