Help me

Answer 1

a, \(\dfrac{5}{8}x-7=\dfrac{437}{14}\Leftrightarrow\dfrac{5}{8}x=\dfrac{525}{14}\Leftrightarrow x=\dfrac{428}{7}\)

b, mình chưa hiểu đề lắm 

Answer 2

a: \(\Leftrightarrow\left(\dfrac{1}{8}+2+\dfrac{5}{4}-\dfrac{11}{4}\right)\cdot x-7=\left(\dfrac{3}{2}+\dfrac{13}{20}+\dfrac{7}{200}\right):\dfrac{7}{100}\)

\(\Leftrightarrow x\cdot\dfrac{5}{8}=\dfrac{535}{14}\)

hay x=428/7
