Answer:
(T/C - 9) / B = A
Explanation:
To solve for A, we want to isolate the variable, which we can do using the following steps:
Step 1: Divide both sides by C:
(T = C(9 + AB)) / C
T/C = 9 + AB
Step 2: Subtract 9 from both sides:
(T/C = 9 + AB) - 9
T/C - 9 = AB
Step 3: Divide both sides by B to solve for A:
(T/C - 9 = AB) / B
(T/C - 9) / B = A
