Question 66718
3(x – 4) > 7x – 9
3x-12 > 7x - 9


Subtract 7x from each side and add +12
3x-7x-12> 7x -7x -9
-4x-12 >-9
-4x-12+12 > -9 +12
-4x >3


Divide both sides by -4, which reverses the inequality sign:
{{{(-4x)/(-4) > 3/(-4)}}}
{{{x< -3/4}}}


On a numberline, this is all values to the left of -3/4.
