\(\dfrac{3x-1}{4}-\dfrac{3\left(x-2\right)}{8}-1>\dfrac{5-3x}{2}\)
MTC : 8
\(\Rightarrow\dfrac{2\left(3x-1\right)}{8}-\dfrac{3\left(x-2\right)}{8}-\dfrac{8}{8}>\dfrac{4\left(5-3x\right)}{8}\)
Suy ra : 2(3x - 1) - 3(x - 2) - 8 > 4(5 - 3x)
\(\Leftrightarrow\) 6x - 2 - 3x + 6 - 8 > 20 - 12x
\(\Leftrightarrow\) 6x - 3x + 12x > 20 + 2 - 6 + 8
\(\Leftrightarrow\) 15x > 24
\(\Leftrightarrow\) x > \(\dfrac{24}{15}=\dfrac{8}{5}\)
Vay x >\(\dfrac{8}{5}\)
