Answer:
A. x ≤ -1 or x > 7
Step-by-step explanation:
-6x+14<-28
or, -6x < -28 - 14 [Changing the side]
or, -6x < -42
or, [tex]\frac{-6x}{-6}[/tex] > [tex]\frac{-42}{-6}[/tex] [Dividing both the sides by -6] [Due to dividing the sides by a negative number, the inequality reverses]
or, x > 7
Therefore, x > 7
3x+28 ≤ 25
or, 3x + 28 - 28 ≤ 25 - 28
or, 3x ≤ -3
or, x ≤ (-3 ÷ 3) [Dividing both the sides by 3]
or, x ≤ -1
Therefore, the answer is x ≤ -1 or x > 7
