Answer:

c = b/(a - 1)

Explanation:

Solve for c:

-1 + 3 a - b/c = 2 a

Bring -1 + 3 a - b/c together using the common denominator c:

(-b - c + 3 a c)/c = 2 a

Multiply both sides by c:

-b - c + 3 a c = 2 a c

Collect in terms of c:

c (3 a - 1) - b = 2 a c

Subtract 2 a c - b from both sides:

c (a - 1) = b

Divide both sides by a - 1:

Answer: c = b/(a - 1)
