21 states
so there are 48 states in the continental US and 7+9=16 which is a third of 48, so you have to multiply the numbers by 3
Sorry i got nothing for you .. but i'll try to solve it shortly.
Most x to the other side: -3y=-x+6
Divide by -3 to get y=x/3+2
The answer is how about no. i want free points :p
This is your answer and shows how to do it
