Question

Cum se rezolva [(x+0,5)•2-0,75]:0,25 ajutati ma va rog urgent!!!!

Answer 1

rezulta (2x+1-0,75):0,25=
(2x+0,25):0,25=
(2x+25/100):25/100=
(2x+1/4):1/4=
[(8x+1)/4]·4= simplificam cu 4
8x=-1
x=-1/8

Answer 2

$[(x+0,5)*2-0,75]:0,25= \\ =(2x+0,5*2-0,75):0,25= \\ =(2x+1-0,75):0,25= \\ =(2x+0,25):0,25= \\ =(2x+ \frac{25}{100} ): \frac{25}{100} = \\ =(2x+ \frac{1}{4} ): \frac{1}{4} = \\ =[\frac{(8x+1) }{4} ]*4= \\ =8x =-1 \\ Rezulta, \ \boxed{x= -0,125}.$
