-8(1/8-1/4у)-3(1-2 1/3у)=
Упростите,заранее спасибо!))))

Answer 1

$-6*( frac{1}{6} - frac{1}{3}y) - 2*(1 - 3 frac{1}{2}y) = -6 * frac{1}{6} + 6* frac{1}{3}y - (2 - 2* frac{7}{2} y ) =$
$= -1 - 2y - (2 - 7y) = -1 + 2y - 2 + 7y = 5y -3$
$-8*( frac{1}{8} - frac{1}{4}y) - 3*( 1 - 2 frac{1}{3}y) = -8* frac{1}{8} + 8* frac{1}{4}y - (3* 3*(- frac{7}{3}y) =$
$-1 + 2y - (3-7y) = -1-2y - 3 +7y = 9y - 4$
