Question

8(5/8y-2 3/4)=4 срочно

Answer 1

Ответ:

y = 26/5

Пошаговое объяснение:

8(5/8y - 2 3/4) = 4 = 2(5/8y - 2 3/4) = 1 = 2(5/8y - 11/4) = 1 = 5/4y - 11/2 = 1 = 5y - 22 = 4 = 5y = 4 + 22 = 5y = 26 = y = 26/5

Answer 2

Ответ: 26/5

Пошаговое объяснение:

$8(\frac{5}{8} y-2\frac{3}{4} )=4$

$\frac{5}{8} y-2\frac{3}{4} =\frac{4}{8}$

$\frac{5}{8} y=\frac{1}{2} +2\frac{3}{4}$

$\frac{5}{8} y=\frac{2}{4} +\frac{11}{4}$

$\frac{5}{8} y=\frac{2+11}{4}$

$\frac{5}{8} y=\frac{13}{4}$

$y=\frac{\frac{13}{4} }{\frac{5}{8} }$

$y=\frac{13}{4} *\frac{8}{5}$

$y=\frac{13}{1} *\frac{2}{5}$

$y=\frac{13*2}{1*5}$

$y=\frac{26}{5}$   или   $y=5\frac{1}{5}$
