Which of the following steps would NOT be a correct step towards solving the equation below:

 $-14x\ -\ 7\ =\ 3x\ +\ 2$  

• Combining  $-14x$  and  $3x$  to get  $-11x.$  

• Adding 7 to both sides of the equation.

• Subtracting 2 from both sides of the equation. 

• Subtracting  $3x$  from  $-14x$  to get  $-17x.$

The Bucks County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides, (r), you would need to go on for both fairs to cost the same?

•  $15r\ +\ 2.5\ =\ 10r\ +\ 3$  

•  $15\ -2.5r\ =\ 10\ -3r$ 

•  $15\ +\ 2.5r\ =\ 10\ +3r$  

•  $15\ -10\ =\ 2.5r\ +\ 3r$
