If 2/(a + 4) = 3/(a - 5), then a = ?	Choose the correct choice from the following choices
A) -20  B) -19  C) -23  D) -21  E) -22
Multiply all terms of the given equation by (a - 5)(a + 4), simplify and solve   (a - 5)(a + 4)[ 2/(a + 4) ] = (a - 5)(a + 4) [ 3/(a - 5) ]   2 (a - 5) = 3 (a + 4)   a = -22   correct answer -22
