Answer:
B = T - 9C/CA
Step-by-step explanation:
1. Switch the sides C(9+AB) = T
2. Divide both sides by C (get rid of what is least attached) C(9+AB)/C and T/C
3. Simplify the equation 9 + BA = T/C
4. Subtract 9, 9+ BA - 9 = T/C - 9
5. Simplify BA = T/C - 9
6. Divide both sides with A like you did with C
