Hi, I've been having trouble with some multi step inequalities.
28-7x<-4(-7x-7)

28-7x<-4(-7x-7)                Expand the RHS

 

28 - 7x < 28x + 28            Subtract 28 from both sides

-7x < 28x                          Subtract 28x from both sides

-35x < 0                            Multiply both sides by -1 and REVERSE the inequality

 35x > 0                             Divide both sides by 35

x > 0
