Question

решите уравнение 1/6x-0,82=3/8x-1,37

Answer 1

Преобразуем уравнение...

((25х-123)150) = ((75x-274)200) => (25x-123)*200 = (75x-274)*150

Ответ: 6625= 2,64.

Answer 2

$frac{1}{6}x-0.82=frac{3}{8}x-1.37$

$frac{x}{6}-0.82=frac{3x}{8}-1.37$

$frac{x}{6}-frac{4.92}{6}=frac{3x}{8}-1.37$

$frac{x-4.92}{6}=frac{3x}{8}-frac{10.96}{8}$

$frac{x-4.92}{6}=frac{3x-10.96}{8}$

$4(x-4.92)=3(3x-10.96)$

$4x-19.68=9x-32.88$

$(4x-9x)-19.68=-32.88$

$-5x-19.68=-32.88$

$-5x=19.68-32.88$

$-5x=-13.2$

$x=2.64$
