Start by distributing the 2 and the -4 on each side of the inequality (multiply the -2 by 3x and by -9; multiple the -4 by 2x and by -9).
That gives you:
Remember, when you multiply the -2 by the -9 on the left, it becomes positive 18.
Since you have 4x - 6x on the left side, you can make that -2x.
Now you have:
Get your variables on one side by adding 8x to both sides, and your numbers on the other by subtracting 18 from both sides and you are left with:
Dividing both sides by 6 gives you the answer:
