Question

Solve the following inequality.

Answer 1

Answer:

A -6 < x ≤ -3

Step-by-step explanation:

21 ≤ - 3(x - 4) < 30

Divide all parts by -3.  Remember that flips the inequalities

21/-3  ≥ - 3/-3 (x - 4) > 30/-3

-7  ≥  (x - 4) > -10

Add 4 to all sides

-7+4  ≥  x - 4+4 > -10+4

-3  ≥  x  > -6

Rearranging the order

-6 < x ≤ -3
