Answer:

a. -10

Explanation:

6 - 2x <= 12 or 7 + 2x < -11

Lets look at the first one first

6 - 2x <= 12

Subtract 6 from each side

6-6 -2x <= 12-6

-2x <= 6

Divide by -2, remembering to flip the inequality

-2x/-2 <=6/-2

x >=-3


Now we solve the second one

7 + 2x < -11

Subtract 7 from each side

7-7 + 2x <-11-7

2x <-18

2x/2 <-18/2

x <-9


Answer x <-9 or x>= -3


-10 is <-9 so it is a solution
