Answer:

D

Step-by-step explanation:

We're looking for the inequality that represents x < -1

Solve each one in turn until we find x < -1

A)

7 + 5x < 19 − 7x

5x + 7x < 19 - 7

12x < 12

x < 1

B)

7 − 5x < 19 + 7x

-5x - 7x < 19 - 7

-12x < 12

-x < 1

C)

7 + 5x > 19 − 7x

5x + 7x > 19 - 7

12x > 12

x > 1

-x < -1

D) 7 − 5x > 19 + 7x

-5x - 7x > 19 - 7

-12x > 12

-x > 1

x < -1
