precal · Answer

quiz is there to assess if you have learned the information.  If it is a prequiz, it is to maybe skip instruction, if it is a post quiz it is to see if you understood the instructions

multiply everything by 3 then add 2a to both sides

anonymous · Answer

k=(1/3)(b-2a) 
multiply 3 both sides
3k=b-2a
add 2a both sides
3k+2a=b-2a+2a 
3k+2a=b 
so, b=3k+2a
