Question

Решите: 1) 4(х-1/2)=0 решите: 2) (х-1 3/4)*2/3=0 решите: 3) 12(х-1 3/10*5/6)=0

Answer 1

$4(x - \frac{1}{2})\\ 4x-4*\frac{1}{2} \\ 4x-2 =0 \\ 4x=2 \\ x=\frac{4}{2} = \frac{1}{2} = 0,5 \\ \\ (x-1 \frac{3}{4})* \frac{2}{3} = 0 \\ (x-\frac{7}{4})* \frac{2}{3} = 0 \\ \frac{2}{3}x - \frac{7}{6} = 0 \\ 4x-7 = 0 \\ 4x=7 \\ x=\frac{7}{4} = 1,75 \\\\ 12(x -1 \frac{3}{10} * \frac{5}{6}) = 0 \\ x-\frac{13}{12} = 0 \\ x= \frac{13}{12} = 1,08333$
