30/100x-x+5/6=1/3
3/10x-x+5/6=1/3
(3/10-1)x+5/6=1/3
(-7/10)x=1/3-5/6
(-7/10)x=-1/2
x=-1/2:(-7/10)
x=5/7
30/100x-x+5/6=1/3
=) 3/10x-x+5/6=1/3
=)(3/10-1)x+5/6=1/3
=)(-7/10)x=1/3-5/6
=)-7/10x=-1/2
=)x=-1/2:(-7/10)
=)x=5/7
vậy x=5/7
xin lỗi câu trả lời vừa r hơi khó nhìn
=) là suy ra
\(30\%x-x+\frac{5}{6}=\frac{1}{3}\)
\(\frac{3}{10}x-x+\frac{5}{6}=\frac{1}{3}\)
\(\frac{3}{10}x-x=\frac{1}{3}-\frac{5}{6}\)
\(-\frac{7}{10}x=-\frac{1}{2}\)
\(x=\frac{5}{7}\)
Vậy \(x=\frac{5}{7}\)
T.i.c.k cho mk nha bn . Thanks
Chúc bn học tốt nha
