Răspuns: [tex]\bf x \in ( -\infty, -\dfrac{3}{2} \Big][/tex]
Explicație pas cu pas:
Salutare!
[tex]\bf 8x+17\leq -2x\cdot4x-7[/tex]
[tex]\bf 8x+17\leq -8x-7[/tex]
[tex]\bf 8x+17 +8x\leq -7[/tex]
[tex]\bf 16x\leq -7-17[/tex]
[tex]\bf 16x\leq -24[/tex]
[tex]\bf x\leq -\dfrac{24}{16}[/tex]
[tex]\bf x\leq -\dfrac{\not24}{\not 16}[/tex]
[tex]\bf x\leq -\dfrac{3}{2}\implies \boxed{\bf x\in( -\infty, -\dfrac{3}{2} \Big]}[/tex]
