(2-3)³/2^6×2^4-1/2=x/2^4 -1/4-1/2=x/16 -(1+2)/4=x/16 -3=x/4
x=-12
11.
(x+2)/(x+1)=1+1/(x+1)
x+1=± 1 x=0 x=-2

[tex](\frac{1}{2} - \frac{3}{4} )^{3} : (-\frac{1}{4} )^{2} -0,5=\frac{x}{16} \\\\(\frac{2-3}{4})^{3}: (-\frac{1}{4} )^{2} - \frac{1}{2} =\frac{x}{16} \\\\(-\frac{1}{4})^{3}: (-\frac{1}{4} )^{2} - \frac{1}{2}=\frac{x}{16}\\\\(-\frac{1}{4} )^{3-2} - \frac{1}{2} = \frac{x}{16} \\\\-\frac{1}{4} - \frac{1}{2} = \frac{x}{16} \\\\ \frac{-1-2}{4} = \frac{x}{16} \\\\\frac{-3}{4} =\frac{x}{16} \\\\4x=-3*16\\\\ 4x= -48\\\\ x = -48:4\\\\\boxed{x = -12}[/tex]

[tex]\frac{x+2}{x+1} \\\\\\\frac{x+1+1}{x+1} = 1 + \frac{1}{x+1} => \\\\x +1 = 1\Rightarrow x= 1-1\Rightarrow\boxed{x=0}\\\\x+1 = -1 \Rightarrow x = -1 - 1\Rightarrow\boxed{x=-2}[/tex]
