4x+4>2-3\left(2x+6\right)
Use the distributive property to multiply 4 by x+1.
4x+4>2-6x-18
Use the distributive property to multiply -3 by 2x+6.
4x+4>-16-6x
Subtract 18 from 2 to get -16.
4x+4+6x>-16
Add 6x to both sides.
10x+4>-16
Combine 4x and 6x to get 10x.
10x>-16-4
Subtract 4 from both sides.
10x>-20
Subtract 4 from -16 to get -20.
x>\frac{-20}{10}
Divide both sides by 10. Since 10 is positive, the inequality direction remains the same.
x>-2
Divide -20 by 10 to get -2.
