REZOLVATI IN MULTIMEA Q ECUATIILE:
x:(-1,8)=6,5
x:(-0,3)=5/21

Va rog urgennnntttt!!!
Dau coroanaaaaa!!!!​

Answer 1

$x:(-1,8)=6,5 \iff x = 6,5 \cdot (-1,8)$

$x = -\dfrac{65}{10} \cdot \dfrac{18}{10} = - \dfrac{117}{10} \implies x = -11,7$

.

$x:(-0,3) = \dfrac{5}{21} \iff x = (-0,3) \cdot \dfrac{5}{21}$

$x = -\dfrac{3}{10} \cdot \dfrac{5}{21} \implies x = -\dfrac{1}{14}$
