Solve the inequality.

–2/3x – 10 <1/3

1 answer

To solve the inequality

\[ -\frac{2}{3}x - 10 < \frac{1}{3}, \]

we will first isolate the term involving \( x \).

  1. Add 10 to both sides:

\[ -\frac{2}{3}x < \frac{1}{3} + 10. \]

  1. Convert 10 to a fraction with a denominator of 3:

\[ 10 = \frac{30}{3}, \] so \[ \frac{1}{3} + 10 = \frac{1}{3} + \frac{30}{3} = \frac{31}{3}. \]

Now the inequality reads:

\[ -\frac{2}{3}x < \frac{31}{3}. \]

  1. Multiply both sides by \( -\frac{3}{2} \) (this reverses the inequality):

\[ x > \frac{31}{3} \cdot -\frac{3}{2}. \]

Calculating the right side:

\[ \frac{31 \cdot -3}{3 \cdot 2} = \frac{-93}{6} = -\frac{31}{2}. \]

Thus, the inequality simplifies to:

\[ x > -\frac{31}{2}. \]

  1. Final solution:

The solution to the inequality is

\[ x > -\frac{31}{2}. \]

This can also be expressed as:

\[ x > -15.5. \]
