5x-20-6\left(x+2\right)<4
Use the distributive property to multiply 5 by x-4.
5x-20-6x-12<4
Use the distributive property to multiply -6 by x+2.
-x-20-12<4
Combine 5x and -6x to get -x.
-x-32<4
Subtract 12 from -20 to get -32.
-x<4+32
Add 32 to both sides.
-x<36
Add 4 and 32 to get 36.
x>-36
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
