Answer:

x > 4 / 5

Step-by-step explanation:

This is similar to solving 7x = 2x + 4, but instead you have an inequality. The only thing you have to watch out for is if you divide by a negative number, if you do, you have to flip the "alligator" sign.

To solve without having to flip:

[tex]7x > 2x + 4\\7x - 2x > 2x - 2x + 4\\5x > 4\\5x/5 > 4 / 5\\x > \frac{4}{5}[/tex]

Solving requiring "alligator" flip:

[tex]7x > 2x + 4\\7x - 7x > 2x - 7x + 4\\0 > -5x + 4\\-4 > -5x\\\frac{-4}{-5} > \frac{-5x}{-5} \\ \frac{4}{5} < x[/tex]
