Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
Answer:
y=12
x=48
Step-by-step explanation:
Relationship shows that
y=1/4x
if we put y=12 and x=48 it holds.
I’m assuming you meant in each shelf there is 14 movies, and there is 4 shelves, so you would multiply 14 x 4 which would be 56 movies
You could do V = b × H 2 × 11 = 22
