To solve for \( c \) in the inequalities:

  1. \(\frac{2c - 11}{3} \geq 3\)
  2. \(\frac{3c - 2}{4} < 4\)

we'll solve each inequality separately.

For the first inequality:

\[ \frac{2c - 11}{3} \geq 3 \]

Multiply both sides by 3 (to eliminate the fraction):

\[ 2c - 11 \geq 9 \]

Add 11 to both sides:

\[ 2c \geq 20 \]

Divide by 2:

\[ c \geq 10 \]

For the second inequality:

\[ \frac{3c - 2}{4} < 4 \]

Multiply both sides by 4:

\[ 3c - 2 < 16 \]

Add 2 to both sides:

\[ 3c < 18 \]

Divide by 3:

\[ c < 6 \]

Combine the results:

We have two inequalities:

  1. \( c \geq 10 \)
  2. \( c < 6 \)

When combined as a compound inequality, since these two inequalities do not overlap (i.e., there are no values of \( c \) that satisfy both conditions at the same time), we write the solution in terms of \( c \):

Final Answer:

\( c \geq 10 \) or \( c < 6 \)

As a compound inequality with integers, the solution can be represented as:

\[ c \in (-\infty, 6) \cup [10, \infty) \]

In terms of integer solutions explicitly:

\[ c < 6 \quad \text{or} \quad c \geq 10 \]

This is the complete solution for \( c \).
