Answer 2

To solve the inequality 12(4-5) > -21y + 3(y-2) < 12y, we need to simplify each inequality separately and then compare the results.

First, let's simplify 12(4-5):

12(4-5) = 12(-1) = -12

Now let's simplify -21y + 3(y-2):

-21y + 3(y-2) = -21y + 3y - 6 = -18y - 6

Finally, let's simplify 12y:

12y

Now we can compare the inequalities:

-12 > -18y - 6 < 12y

To solve for y, we will isolate y in the middle inequality:

-12 + 18y > -6

Add 12 to both sides:

18y > 6

Divide both sides by 18:

y > 1/3

So the solution for y is y > 1/3.
