Answer 2

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 (-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
