3A - 10B = 3*[-2 4] - 10 * [-6 2]
= [-6 12] - [-60 20]
= [54 -8]

What are the numbers 0 3 4 0 doing at the back of the question?
Well anyway
3A - 10B
= 3 [-2 4] - 10 [-6 2]
= [-6 12] - [-60 20]
= [54 -8]

if I read your question correctly:
A = [-2, 4; 0 , 3]
B = [-6, 2; 4 , 0]
so 3A - 10B = [-6 + 60, 12 - 20; -40, 9]
= [ 54, -8; -40, 9]
first row is 54 and -8
second row is -40 and 9

3A = [-6 12]
10B = [-60 20]
3A - 10B = [-6+60 12-20] = [54 -8]
