syms T1 T2 T3 T4 T5 T6
T = [T1 T2 T3 T4 T5 T6];
d = -5;
G = [10 1 5];
vpasolve([T*A - d*T == G*C])
After solving for the values of T1 to T6, i want to use those values to solve for another equation, but when I input T1,T2... into the other equation, it returns the answer in terms of T1 - T6 instead of actual values
e = T*B
how do i get it to return the actual numbers instead of in terms of T1 etc.?

You don't need symbolic computations.
