If -3/(a - 3) = 3/(a + 2), then a = ?
Choose the correct choice from the following.
A) 1 / 2  B) 2 / 3  C) 3 / 4  D) 4 / 5  E) 5 / 6

Rationale: multiply all terms of the given equation by ( a - 3 ) ( a + 2 ) , simplify and solve ( a - 3 ) ( a + 2 ) [ - 3 / ( a - 3 ) ] = ( a - 3 ) ( a + 2 ) [ 3 / ( a + 2 ) ] - 3 ( a + 2 ) = 3 ( a - 3 ) a = 1 / 2 correct answer a
Answer: A
