=> 1 - (43/8+x-173/24) = 0
=> 43/8 + x - 173/24 = 1
=> 43/8 + x = 197/24
=> x = 17/6
k nha
\(\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=2\)
\(\Rightarrow\frac{43}{8}+x-\frac{173}{24}=\frac{100}{3}\)
\(\Rightarrow x-\frac{11}{6}=\frac{100}{3}\)
\(\Rightarrow x=\frac{211}{6}\)
\(=>\dfrac{43}{8}+x=-\dfrac{46}{3}+\dfrac{173}{24}=-\dfrac{65}{8}\)
\(=>x=-\dfrac{65}{8}-\dfrac{43}{8}=-\dfrac{27}{2}\)
x=-46/3 +173/24 -43/8
x= 368/24 + 173/24 -129/24
x=103/6
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) \(\Leftrightarrow\left(\frac{43}{8}+x-\frac{173}{24}\right).-\frac{3}{50}=1\Leftrightarrow\frac{-11}{6}+x=-\frac{50}{3}\Leftrightarrow x=-\frac{37}{2}\)
