Answer:
x<-1
Step-by-step explanation:
12x>7(4x+5)-19
<u><em>Solve the right side</em></u>
12x > 28x+35-19
12x > 28x+16
<u><em>Make x the subject</em></u>
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.
<u><em>Simplify</em></u>
x < -1
The inequality of x is x<-1
