Cramers rule debugging help

[a1 a2 a3; b1 b2 b3; c1 c2 c3]= input(' matrices')
A= [a1 a2 a3;b1 b2 b3;c1 c2 c3]
[x1; x2; x3]= input('right hand side matrices')
x= [x1 ;x2 ;x3]
Ax=[ x1 a2 a3;x2 b2 b3;x3 c2 c3]
Ay=[ a1 x1 a3;b1 x2 b3; c1 x3 c3]
Az=[ a1 a2 x1;b1 b2 x2; c1 c2 x3]
det(A)=det(A)
x = det(Ax)/detA
y = det(Ay)/detA
z = det(Az)/detA

this is the function that i wanna run as cramer rule in my matlab, but when i execute the code, it says that

multiple left hand sides must be seperated by commas

can anyone solve my problem? Providing any modification on my function would be appreciated.
