a) Using cross multiplication, you would get: 9b + 6 = 30.

   This means that 9b = 24, so b = 24/9.

   24/9 can be simplified into 8/3

   b = 8/3

b) Using the same method as before- cross multiplication...

   12 - 3f = 5f + 5.

   This means 8f + 5 = 12.

   So you simplify it to 8f = 7.

   f = 7/8
