For this case we must find the solution of the following system of inequalities:


3x-4 \leq2 or
2x + 11 \geq-1

Inequality 1:


3x-4 \leq2

We add 4 to both sides of the inequality:


3x \leq2 + 4\\3x \leq6

We divide between 3 on both sides of the inequality:


x \leq \frac {6} {3}\\x \leq2

Thus, the solution is given by all values of x less than or equal to 2.

Inequality 2:


2x + 11 \geq-1

We subtract 11 from both sides of the inequality:


2x \geq-1-11\\2x \geq-12

We divide between 2 on both sides of the inequality:


x \geq \frac {-12} {2}\\x \geq-6

Thus, the solution is given by all values of x greater than or equal to -6.

Thus, the solution set is given by:

(-∞, - 2] U [-6,∞)

That is, the solution set is given by all real numbers.

Answer:

All real numbers
