Solving Equations with Variables on both Sides

Quinda begins to solve the equation  by adding 8.5x to each side of the equation. Which next step would result in the variable terms and constant terms being on different sides of the equals sign?

 $-4.5x+3=2\ -8.5x$  

• Subtract 4x from both sides.

• Subtract 2 from both sides.

• Add 4x to both sides.

• Subtract 3 from both sides.
