Step 1. Simplify brackets

-3x + 7 -4(2x - 6) -12 > 7

Step 2. Cancel 7 on both sides

-3x -4(2x - 6) -12 > 0

Step 3. Expand

-3x - 8x + 24 - 12 > 0

Step 4. Simplify -3x - 8x + 24 - 12 to -11x + 12

-11x + 12 > 0

Step 5. Subtract 12 from both sides

-11x > -12

Step 6. Divide both sides by -11

x < -12/-11

Step 7. Two negatives make a positive

x < 12/11
