Solve the inequality -3(3x-8)<-12x+6 Help ?

OpenStudy (tkhunny):

-3(3x-8) < -12x + 6 Resolve the parentheses -9x + 24 < -12x + 6 Add 12x 3x + 24 < 6 Now what?

OpenStudy (tkhunny):

-3(3x-8) < -12x + 6 You may wish to divide by -3. This works, okay, but then YOU must remember to switch the inequality. 3x - 8 > 4x - 2 The first way, the notation worries about that for you.
