Question

Solve . Write your solution using set builder notation
-2(10x-9)-17x<12(6-x)

Answer 1

-(20x-18)-17x<-x+12
-36x<-12
x>1/3
but what is builder notation

Answer 2

-17 x-2 (-9+10 x)<12 (6-x)
= -17 x-2 (-9)-2 10 x<12 6+12 (-1) x
= -17 x-9 (-1) 2-2 10 x<6 12-12 x
= -17 x-18 (-1)-2 10 x<72-12 x
= -17 x+18-20 x<72-12 x
= 18-37 x<72-12 x
x>-54/25
