Answer:

x<-1

Step-by-step explanation:

12x>7(4x+5)-19

Solve the right side

12x > 28x+35-19

12x > 28x+16

Make x the subject

12x-28x > 16

-16x > 16

-x > 16/16

-x > 1

Multiplying by -1 on both sides

x < -1  

If you multiply ">" with minus sign, its direction changes. It is similar to switching the positions of x and -1.  

Simplify

x < -1

The inequality of x is x<-1
