Question

0,25x - \(\dfrac{27}{8}\) x= \(\dfrac{-3}{4}\)                   

Answer 1

Lời giải:

$0,25x-\frac{27}{8}x=\frac{-3}{4}$

$x(0,25-\frac{27}{8})=\frac{-3}{4}$

$x.\frac{-25}{8}=\frac{-3}{4}$

$x=\frac{-3}{4}: \frac{-25}{8}=\frac{6}{25}$

Answer 2

0,25x - 27/8x = -3/4

1/4x - 27/8x = -3/4
x . ( 1/4 - 27/8 ) = -3/4
x . -25/8 = -3/4
x = -3/4 : -25/8 
x = -3/4 . -8/25
x = -6/25
