Question

(x+0,1)*3+8=0

Answer 1

\(\Rightarrow x+\dfrac{1}{10}=-\dfrac{8}{3}\Rightarrow x=-\dfrac{83}{30}\)

Answer 2

(x+0,1).3+8=0

⇔(x+0,1).3=-8

⇔x+0,1=\(-\dfrac{8}{3}\)

⇔x=\(-\dfrac{83}{30}\)

Answer 3

$(x+0,1).3+8=0$

$\Rightarrow (x+0,1).3=-8$

$\Rightarrow (x+0,1)=\dfrac{-8}{3}$

$\Rightarrow x=\dfrac{-8}{3}-0,1=\dfrac{-83}{30}$
