3(x+2)-6x+6<0 "< is like equal sign bruv"
3x+6-6x+6<0 "do group so ( ) so multiply and bring everything else down"
-3x+12<0 "add all like terms so "3x-6x" and "6+6" since they cancel out you get "
-3x< 0-12 "to get rid of 12 you subtract 12 and subtract it from the other side so 0 aswell
-3x<-12 "you would end up with this"
-3x/-3 < -12/-3 "since dividing or multiplying by a negative you flip the arrow"
x > 4 "this is the answer"
