Let's simplify the following inequality:


\text{ 4 - \lparen x + 2\rparen < -3\lparen x + 4\rparen}

We get,


\text{ 4 - \lparen x + 2\rparen < -3\lparen x + 4\rparen}
\text{ 4 - x - 2 < -3x - 12}
\text{ -x + 3x < -12 - 4 + 2}
\text{ 2x < -14}
\text{ }\frac{\text{ 2x}}{\text{ 2}}\text{ < }\frac{\text{ -14}}{\text{ 2}}
\text{ x < -7}

Therefore, the answer is CHOICE A : x < -7
