Giúp mik vs cần gấp. Cảm ơn 🤍

· $\frac{2x-1}{5-3x}=2$ 

$\Longleftrightarrow2x-1=2×(5-3x)$

$\Longleftrightarrow2x-1=10-6x$ 

$\Longleftrightarrow8x=11$

$\Longleftrightarrow$$x=\frac{11}{8}$ 

· $\frac{4x-5}{x-1}=2+\frac{x}{x-1}$ 

$\Longleftrightarrow$$\frac{4x-5}{x-1}-\frac{x}{x-1}=2$

$\Longleftrightarrow$$\frac{3x-5}{x-1}=2$ 

$\Longleftrightarrow3x-5=2×(x-1)$

$\Longleftrightarrow3x-5=2x-2$

$\Longleftrightarrow$$x=3$

· $\frac{12x}{11x-4}+\frac{10x-4}{9}=\frac{20x+17}{18}$ 

$\Longrightarrow12x×9×18+(10x-4)×18×(11x-4)=(20x+17)×9×(11x-4)$

$\Longleftrightarrow$$1944x+(180x-72)×(11x-4)=(180x+153)×(11x-4)$

$\Longleftrightarrow1944x+1980x^{2}-720x-792x+288=1980x^{2}-720x+1683x-612$

$\Longleftrightarrow$$-531x=-900$

$\Longleftrightarrow$$x=\frac{100}{59}$
