Question

rezolvati in Q ecuatiile:(3 supra4+5 supra6):1,58(3)-4 supra5 x=1 supra2;(2x+3 supra9+0,(3)):0,5+3 intregi si 1 supra4 totul supra5,25=2011^0

Answer 1

(3/4+5/6):1,58(3)-4x/5=1/2
(9+10)/12 :(1583-158)/900-4x/5=1/2
19/12 ×900/1425-4x/5=1/2
19/1 ×75/1425-4x/5=1/2
19/1 ×1/19-4x/5=1/2
-4x/5=1/2
x=-5/8

[(2x+3/9+0,(3)):0,5+3 intregi si 1/4]/5,25=2011⁰
[(2x+1/3+1/3): 1/2+13/4]/ (525/100)=1
[(2x+2/3)×2+13/4]/ (21/4)=1
([2x+2/3)×2+13/4] ×4/21=1
(2x+2/3)×2+13/4=21/4
(2x+2/3)×2=21/4 -13/4
(2x+2/3)×2=8/4
(2x+2/3)×2=2
2x+2/3=1
2x=1-2/3
2x=1/3
x=1/6
