Answer:
x<7
Step-by-step explanation:
12x-3x +11 > 4x - (17-9x) combine like terms
9x+11>4x - (17-9x) simplify
9x+11> 13x -17 move like terms, then combine
-4x>-28 divide to isolate the variable
12x-3x +11 > 4x - (17-9x)
9x+11 > 4x-17+9x
9x+11 > 13x-17
9x-13x > - 17 - 11
- 4x > - 28
x < 7
or
x ∈ 《- ∞ , 7 》
