Question

Решите уравнение:
$2(X+ 1 frac{1}{6})-2 frac{2}{3}=1.5$

как дальше:
$2(X+1 frac{1}{6})=- frac{5}{6}$

Answer 1

$1) 2(x+1 frac{1}{6})-2 frac{2}{3}=1,5 \ 2(x+1 frac{1}{6})=1,5+2 frac{2}{3} \ 2(x+1 frac{1}{6})=1 frac{3}{6} +2 frac{4}{6} \ 2(x+1 frac{1}{6})=4 frac{1}{6} \ 2x+2 frac{2}{6}= 4 frac{1}{6} \ 2x=4 frac{1}{6}-2 frac{2}{6 }\ 2x=1 frac{5}{6} \ x=1 frac{5}{6} :2 \ x= frac{11}{12} \ 2) 2(x+1 frac{1}{6} )=- frac{5}{6} \ x+1 frac{1}{6}=- frac{5}{6} :2 \ x+1 frac{1}{6}=- frac{5}{12} \ X=- frac{5}{12}-1 frac{1}{6} \ X=-1 frac{7}{12}$

Answer 4

2(X+7/6)-8/3=3/2
2X+7/3-8/3=3/2
2X=3/2+1/3
2X=9/6+2/6
2X=11/6
X=11/12

2(X+7/6)=-5/6
2X+14/6=-5/6
2X=-19/6
X=-19/12
X=-1 7/
