\bf{4(3x + 2) < 5(3x - 2)}

Simplify both sides of the inequality.


  • \bf{12x+8 < 15x-10}

Subtract 15x from both sides.


  • \bf{12x+8-15x < 15x-10-15x}

  • \bf{-3x+8 < -10}

Subtract 8 from both sides.


  • \bf{-3x+8-8 < -10-8 }

  • \bf{-3x < -18}

Divide both sides by -3.


  • \bf{(-3x)/(-3) < (-18)/(-3) }

  • \bf{x > 6 \ \ \to \ \ \ Answer}
