x>=-4

Explanation:

Solve -3x-12<=3x+12

Add 3x to both sides and simplify.

-12<=3x+12+3x

-12<=6x+12

Subtract 12 from both sides and simplify.

-12-12<=6x

-24<=6x

Divide both sides by 6 and simplify.

-24/6<=x

-4<=x

Switch sides.

x>=-4

x>= -4

Explanation:

We can start by adding 12 to both sides to get

-3x<=3x+24

Next, we can subtract 3x from both sides to get

-6x<=24

Lastly, we can divide by -6 on both sides. Since we are dividing by a negative, we must flip the inequality. We get

x>= -4

Hope this helps!
