If 9a - b = 10b + 80 = -12b - 2a, what is the value of 9a - 11b? Choose the correct choice from the following options:
A) -4  B) -2  C) 0  D) 2  E) 80
This implies 9a - b = 10b + 80, 9a -b = -12b -2a, 10b + 80 = -12b -2a   Manipulating the second equation gives us 9a - b = 10b +80 ==&gt; 9a - 11b = 80   Answer is 80
