Answer 1

Answer:

hope you got the answer and best of luck

Answer 2

$\dfrac{(x \: - \: 1)}{5} \: - \: \dfrac{3(x \: - \: 1)}{10} \: = \: 2$

___________ [GIVEN]

• We have to find the value of x.

______________________________

$\implies\:\dfrac{(x \: - \: 1)}{5} \: - \: \dfrac{3(x \: - \: 1)}{10} \: = \: 2$

$\implies\:\dfrac{(x \: - \: 1)}{5} \: - \: \dfrac{(3x \: - \: 3)}{10} \: = \: 2$

$\implies\:\dfrac{2(x \: - \: 1) \: - \: 3x \: + \: 3}{10} \: = \: 2$

$\implies\:\dfrac{2x \: - \: 2 \: - \: 3x \: + \: 3}{10} \: = \: 2$

$\implies\:\dfrac{ - x \: + \: 1}{10} \: = \: 2$

$\implies\:-\:x\:+\:1\:=\:2\:\times\:10$

$\implies\:-\:x\:=\:20\:-\:1$

$\implies\:-\:x\:=\:19$

$\implies\:x\:=\:-\:19$
