8\left(-x+2\right)-\left(x+4\right)>3x+12
Multiply both sides of the equation by 6, the least common multiple of 3,6,2. Since 6 is positive, the inequality direction remains the same.
8\left(-x\right)+16-\left(x+4\right)>3x+12
Use the distributive property to multiply 8 by -x+2.
8\left(-x\right)+16-x-4>3x+12
To find the opposite of x+4, find the opposite of each term.
8\left(-x\right)+12-x>3x+12
Subtract 4 from 16 to get 12.
8\left(-x\right)+12-x-3x>12
Subtract 3x from both sides.
8\left(-x\right)+12-4x>12
Combine -x and -3x to get -4x.
8\left(-x\right)-4x>12-12
Subtract 12 from both sides.
8\left(-x\right)-4x>0
Subtract 12 from 12 to get 0.
-8x-4x>0
Multiply 8 and -1 to get -8.
-12x>0
Combine -8x and -4x to get -12x.
x<0
Product of two numbers is >0 if both are >0 or both are <0. Since -12<0, x must be <0.
