Question

решите 1/3•(2х+1)+2•1-х)=3 1/3

Answer 1

$frac{1}{3} times (2x + 1) + 2 times (1 - x) = 3 frac{1}{3} \ frac{2}{3} x + frac{1}{3} + 2 -2 x = 3 frac{1}{3} \ - 1 frac{1}{3} x = 3 frac{1}{3} - 2 frac{1}{3} \ - 1 frac{1}{3} x = 1 \ x = 1 div ( - 1 frac{1}{3} ) = 1 div (- frac{4}{3} ) = 1 times ( - frac{3}{4} ) = - frac{3}{4} \ x = - frac{3}{4}$
