Answer:
The fourth selection is the most appropriate
Explanation:
Next steps are to put all the constants on one side of the equal sign and all the variable terms on the other side.
Among the choices offered, the only one that makes a positive contribution to that strategy is the last one: subtract 600x from both sides of the equation.
_____
Personally, I would combine the terms on the left, then add their opposite, 334x. This would result in the x-term having a positive coefficient. The choice offered here (subtract 600x) results in an x-term with a coefficient of -934. That works just as well, provided you're not confused or intimidated by arithmetic with negative numbers.
