=> 1 - (43/8+x-173/24) = 0
=> 43/8 + x - 173/24 = 1
=> 43/8 + x = 197/24
=> x = 17/6

\(2-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=0\)
\(\left(x-\frac{11}{6}\right)\cdot\frac{3}{50}=2\)
\(\Rightarrow x-\frac{11}{6}=\frac{100}{3}\)
\(\Rightarrow x=\frac{211}{6}\)
a) \(\frac{1}{3}x+\frac{2}{5}x+\frac{2}{5}=0\Leftrightarrow\frac{11}{15}x=-\frac{2}{5}\Leftrightarrow x=-\frac{6}{11}\)
b) \(\Leftrightarrow\left(\frac{43}{8}+x-\frac{173}{24}\right).-\frac{3}{50}=1\Leftrightarrow\frac{-11}{6}+x=-\frac{50}{3}\Leftrightarrow x=-\frac{37}{2}\)
2 - ( 2/8 + x - 173/24 ) : 50/3 = 0
( 2/8 + x - 173/24 ) : 50/3 = 2 - 0
( 2/8 + x - 173/24 ) : 50/3 = 2
2/8 + x - 173/24 = 2 x 50/3
2/8 + x - 173/24 = 100/3
2/8 + x = 100/3 + 173/24
2/8 + x = 973/24
x = 973/24 - 2/8
x = 967/24
\(2-\left(\frac{2}{8}+x-\frac{173}{24}\right)\text{ : }\frac{50}{3}=0\)
\(2-\left(\frac{2}{8}+x-\frac{173}{24}\right)=0\text{ x }\frac{50}{3}\)
\(2-\left(\frac{2}{8}+x-\frac{173}{24}\right)=0\)
\(\frac{2}{8}+x-\frac{173}{24}=2-0\)
\(\frac{2}{8}+x-\frac{173}{24}=2\)
\(\frac{2}{8}+x=2+\frac{173}{24}=\frac{48}{24}+\frac{173}{24}\)
\(\frac{2}{8}+x=\frac{221}{24}\)
\(x=\frac{221}{24}-\frac{2}{8}=\frac{221}{24}-\frac{6}{24}\)
\(x=\frac{215}{24}\)
Cho mình hỏi: 42/8:; 173/24; 50/3 là phân số phải ko??
1-(42/8+x-173/24):50/3=0
(42/8+x-173/24):50/3=0+1=
(42/8+x-173/24):50/3=1
(42/8+x-173/24) : 16,66=1
(42/8+x-173/24) = 1+16,66
(42/8+x-173/24) =17,66
5,25+x-7,20833=17,66
5,25+x=17,66+7,20833
5,25+x= 24,86433
x=24,86433-5,25
x=.......tự tính
