Given that the solution set of inequality 5x x a < 3 is x < 2, try to find the value of A
-7
Solving inequality - x + 5x-6 ≥ 0
-x+5x-6≥0 (-1+5)x-6≥0 4x≥6 x≥3/2
The inequality of solution about X: (1) (x-3) (x + 2) > 0 (2) (5x-6) / (2x + 1)
(1)(x-3)(x+2)>0
x3
(2)(5x-6)/(2x+1)
5x-2/3(1+x)=
5x-2/3(1+x)=
