-2(3x+2) is greater than or equal to -6x-4

olchik [2.2K]

The inequality would look like this:

-2 (3x + 2) $\geq$ -6x-4

To begin to find the solutions, distribute the -2 throughout the set of parenthesis on the left side of the inequality by multiplying the -2 by each term in the set of parenthesis

-2 x 3x = -6x
-2 x 2 = -4

-6x -4 $\geq$ -6x-4

Begin to isolate x by performing the opposite operation of adding -6x on both sides of the inequality

0x -4 $\geq$ -4

Next perform the opposite operation by adding 4 on both sides of the inequality

0x $\geq$ 0

Now, I'm not exactly understanding how that can possibly work. So, I guess I didn't really help you. But add a comment so that we can talk about the problem :)
