Answer

x>277x > \frac{27}{7}

Step-by-step solution

2 steps

Let's solve this inequality.

  1. Gather all terms involving xx on one side and constant terms on the other side of the inequality.

    Subtract 2x2x from both sides:

    30−5x−2x<330 - 5x - 2x < 3 30−7x<330 - 7x < 3

    Subtract 30 from both sides:

    −7x<3−30-7x < 3 - 30 −7x<−27-7x < -27
  2. Isolate xx by dividing both sides by −7-7.

    When dividing or multiplying an inequality by a negative number, remember to reverse the inequality sign.

    −7x−7>−27−7\frac{-7x}{-7} > \frac{-27}{-7} x>277x > \frac{27}{7}
