hello lets say i have this code :
syms x y c
X=[x ;y]
A=[3 -9; c 4]
B=[-42 ;2 ]
eqn=B==A*X
S=solve(eqn, x,y)
x=S.x
y=S.y
and I get answer of x and y , then lets say that I want C=3 and insert it to to x and get numerical answer , how do I make it happen ?

x=subs(x,3)

Using the cell arrays as cvklpstunc shows is the more robust way, needed when vectors or arrays are being substituted for variables. But in the case of scalars, you can also use, for example,
eq = subs(eq, [a, b, c, d, e], [1, 2, 3, 4, 5])
with [] instead of {}. There are times when this is easier to use
