Răspuns: [tex]S=\{-2,-1\}[/tex]
Explicație pas cu pas:
Salutare!
[tex]\bf A = \{-2,-1,0,1,2\}[/tex]
[tex]\bf 3x-2\cdot(x+1)\leq -3[/tex]
[tex]\bf 3x-2x-2\leq -3[/tex]
[tex]\bf x-2\leq -3[/tex]
[tex]\bf x\leq -3+2[/tex]
[tex]\bf x\leq -1[/tex]
[tex]\bf x\in (-\infty ,-1][/tex]
[tex]\bf A \cap (-\infty ,-1]\implies \bf \{-2,-1,0,1,2\} \cap (-\infty ,-1]\implies \boxed{\bf S=\{-2,-1\}}[/tex]
