Question

Solution for the inequality: 12x-3x +11 > 4x - (17-9x)

Answer 1

Explanation:

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 》

Answer 2

x<7

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

x<7
