Question

Solve 7 / 2 x = 5 / 20 x - 8​

Answer 1

Answer:

7/2x = 5/20x - 8

=> 7(20x-8) = 5×2x

=> 140x-56 = 10x

=> 140x-10x = 56

=> 130x = 56

=> x = 56/130.

therefore, Value of X = 28/65. ans......

Answer 2

Question :

• ${\sf{\dfrac{7}{2 x}~=~\dfrac{5}{20 x}~-~8}}$

Solution :

$~~~~~~~~~~{\sf:\implies{7\bigg(20 x~-~8\bigg)~=~5~×~2 x}}$

$~~~~~~~~~~{\sf:\implies{140 x~-~56~=~10 x}}$

$~~~~~~~~~~{\sf:\implies{140 x~-~10 x~=~56}}$

$~~~~~~~~~~{\sf:\implies{130 x~=~56}}$

$~~~~~~~~~~:\implies\underset{\blue{\rm Required\ Answer}}{\underbrace{\boxed{\frak{\pink{x~=~\dfrac{56}{130}}}}}}$

Hence,

$\therefore\underline{\sf{The~ Value~of ~\bf{x}~\sf{is}~\bf{\dfrac{28}{65}}}}$
