Selesaikan dan tuliskan hp dari ptrlk x+2 per x-1 >3 (x+3 per x+1) -2

(x+2)/(x-1) > 3{(x+3)/(x+1)} - 2
(x+2)/(x-1) > (3x+9)/(x+1) - 2(x+1)/(x+1)
(x+2)/(x-1) > (3x+9)/(x+1) - (2x+2)/(x+1)
(x+2)/(x-1) > (3x+9-2x-2)/(x+1)
(x+2)/(x-1) > (x+7)/(x+1)
(x+2)/(x-1) - (x+7)/(x+1) > 0
{(x+2)(x+1) - (x+7)(x-1)} / (x-1)(x+1) > 0
(x²+3x+2-x²-6x+7) / (x-1)(x+1) > 0
(-3x+9) / (x-1)(x+1) > 0
