Question

X/5 -4 = -0,1 x +2
4 1/6 - 1 1/3 x = 4 x + 3 5/18
Решите пожалуйста

Answer 1

$frac{x}{5} - 4 = - 0.1x + 2 \ x - 20 = - 0.5x + 10 \ 1.5x = 30 \ x = 30 div 1.5 \ x = 20 \ \ 4 frac{1}{6} - frac{11}{3} x = 4x + 3 frac{5}{18} \ 4x + 3 frac{2}{3} x = 4 frac{1}{6} - 3 frac{5}{18} = \ 7 frac{2}{3} x = 4 frac{3}{18} - 3 frac{5}{18} = frac{16}{18} \ frac{23}{3} x = frac{8}{9} \ x = frac{8}{9} div frac{23}{3} = frac{8}{69}$
