The answer is y $\leq$ $\frac{10-4x}{-5}$.

Work Step by Step

To solve this inequality for y, you would have to subtract 4x from both the sides leaving -5y $\geq$ 10-4x. Next, you divide -5 from both the sides isolating y. BUT you have to flip the sign of the inequality to $\leq$ because you are dividing from a negative number. So, the answer on top is correct.
