Solve the following inequalities

2x<15

-2y<15

2x<-15

1 answer

Let's solve each inequality separately.

  1. For the inequality \( 2x < 15 \):

    Divide both sides by 2: \[ x < \frac{15}{2} \] Simplifying the right-hand side gives: \[ x < 7.5 \]

  2. For the inequality \( -2y < 15 \):

    Divide both sides by -2. Remember that when you divide or multiply by a negative number, you must flip the inequality sign: \[ y > \frac{15}{-2} \] Simplifying the right-hand side gives: \[ y > -7.5 \]

  3. For the inequality \( 2x < -15 \):

    Divide both sides by 2: \[ x < \frac{-15}{2} \] Simplifying the right-hand side gives: \[ x < -7.5 \]

Summary of Solutions:

  1. \( x < 7.5 \)
  2. \( y > -7.5 \)
  3. \( x < -7.5 \)

These inequalities describe the ranges of values for \( x \) and \( y \).
