Question

Rezolvati in Q inecuatia :
X-2 supra 4 - x+1 supra 6 = 1 supra 6
Va rog ..

Answer 1

x-2 supra 4-x+1 supra 6= 1supra 6 (acum,aducem la acelasi numitor)
3x-6 supra 12 - 2x+2 supra 12 = 2 supra 12
3x-6-2x+2=2
3x-2x-6+2=2
1x-4=2
1x=2+4
1x=6
x=6:1
x=6
S= {6}

Answer 2

$\displaystyle \frac{x-2}{4} - \frac{x+1}{6} = \frac{1}{6} \\ 3(x-2)-2(x+1)=2 \cdot 1 \\ 3x-6-2x-2=2 \\ 3x-2x=2+6+2 \\ x=10$
