whats the answer to -3(2x+7)<-9x-15

Question

i need help with the answer

Answer 1

-3(2x+7)<-9x-15

First off when do ing inequalities, The <, Flips ( Changes Direction ), When dividing by a negitive number.

 

ok so First Distribute the -3,

-6x -21 < -9x -15 Ok, now Get one x value alone, (doesnt matter what one eigher way youll get the same answer).

So i will +21

-6x < -9x +6 Add your remaining x's over from the side with the 6 so and the like terms are together

3x < 6 Divid by 3

x< 2 Sign doesnt flip because it was a positive number being divided..

To graph this, know that it would be an Open Circle To the Left Direction.
