Answer:

A.) x = 21.4

Explanation:

When solving the inequality, you can treat the sign like an equal sign. To isolate the "x" variable, you can add "4" to both sides. This eliminates the -4 from the right side.

You are left with the inequality:

x > 19.5

If "x" must be greater than 19.5, the only answer that satisfies this is A.) x = 21.4. All of the other answers are less than 19.5.

\bf{x -4 > 15.5}


\bf{Add \ 4 \ to \ both \ sides.}


\bf{x-4+4 > 15.5+4 }


\bf{x > 19.5 === > Answer }
