Question

0,6(y-3)-0,5(y-1)=1,5

Answer 1

$0.6(y - 3) - 0.5(y - 1) = 1.5$

$0.6y - 1.8 - 0.5y + 0.5 = 1.5$

$0.1y - 1.3 = 1.5$

$0.1y = 1.5 + 1.3$

$0.1y = 2.8$

$y = frac{2.8}{0.1} = 28$

Ответ : 28

Answer 2

Ответ:

y=28

Пошаговое объяснение:

$0.6(y - 3) - 0.5(y - 1) = 1.5 \ 0.6y - 1.8 - 0.5y + 0.5 = 1.5 \ 0.1y - 1.3 = 1.5 \ 0.1y = 2.8 \ y = 28$
