Question

modul x+2 =0,8(3) va rog

Answer 1

Modul x+2 = 0,8(3)
x+2=0,8(3) SAU  x+2= -0,8(3)
x+2=$\frac{5}{6}$
$\frac{6x+12}{6}$ = $\frac{5}{6}$
6x+12=5
x= -$\frac{7}{6}$
SAU
x+2 = -$\frac{5}{6}$
$\frac{6x+2}{12}$ =  - $\frac{5}{6}$
6x+12= -5
6x= - 17
x= -$\frac{17}{6}$
x ∈ -$\frac{17}{6}$ ȘI $\frac{7}{6}$
