The correct answer is C, x is greater than -5. In order to solve this, you have to solve for x by simplifying both sides of the equation. Then you have to isolate the variable. Hope this helped!
Let's begin by combining like terms. Adding 2x to both sides of this inequality yields -4 < 5x + 21. Next we combine the constant terms, obtaining -25 < 5x, or x > -5. This correspondes to answer choice C.
