Question

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

Answer 1

For this case we have the following inequality:
 $2(x-1) \geq -12$
 Rewriting the inequality we have:
 $2x-2 \geq -12$
 From here, we clear the value of x.
 We have then:
 $2x \geq -12+2$
 $2x \geq -10$
 $x \geq \frac{-10}{2}$
 $x \geq -5$
 Therefore, the solution is given by the interval:
 [-5,∞)
 Answer:
 the following is not a way to represent the solution of the inequality:
 x less than or equal to −5
