How would you solve equations with 3 sides or whatever this is

B. -4 < y < -1

Step-by-step explanation:

1. Subtract 2 from all three sides to isolate the variable in the center of the inequality

5 < 2 - 3y < 14

3 < -3y < 12

2. Divide each of the three sides by -3 to get y by itself, as each of the answers have y as independent.

3 < -3y < 12

-1, y, -4

3. Rearrange

-4 < y < -1 (b)

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
