Question

Решите уравнение 3/5х-1/3х= 6 1/4 2) (2х-1/8х) :1/2=1/3

Answer 1

$frac{3}{5}x- frac{1}{3}x=6 frac{1}{4}$
$frac{9}{15}x- frac{5}{15}x=frac{25}{4}$
$frac{4}{15}x=frac{25}{4}$
$x=frac{15*25}{4*4}$
$x=frac{375}{16}$
$x=23 frac{7}{16}$
2)
$2x- frac{1}{8}x= frac{1*2}{3}$
$frac{16}{8} x- frac{1}{8}x= frac{2}{3}$
$frac{15}{8} x= frac{2}{3}$
$x= frac{2*8}{3*15}$
$x= frac{16}{45}$
