Answer:
a=2, z= 4.75, m=4, k=3
Step-by-step explanation:
In Matrix Addition, each element in corresponding position is added.
In Matrix Equality, elements in the same position are equal.
Applying these two principles
a+7+12a=33
13a=33-7
13a=26
a=2
2z+1+6z=39
8z=39-1
8z=38
z= 4.75
3m+5m=32
8m=32
m=4
6k+7k=39
13k=39
k=3
Therefore:
a=2, z= 4.75, m=4, k=3
