Răspuns:A = (-1,1)
B = [-7,7]
C = -2 < x-3 < 2 => -5 < x < -1 => (-5,-1)
D = -5 [tex]\leq [/tex] [tex]\frac{x-1}{4} [/tex] [tex]\leq [/tex] 5 => amplificam cu 4 => -20 [tex]\leq \\ [/tex] x-1 [tex]\leq \\ \\ \\ \\ \\ [/tex]20 => -21[tex]\leq [/tex]x[tex]\leq [/tex]19 => [-21,19]
E = -11< [tex]\frac{2x-4}{3} [/tex]<11 => amplificam cu 3 => -33<2x-4<33 => -37<2x<29 => -74<x<58 => (-74,58)
