13. 5x -
1/3(x + 1) = 6 (x +1/30)
​

Answer 1

☆Question☆

$\sf\green {5x - \frac{1}{ 3} (x + 1) = 6( x + \frac{1}{30} )}$

☆Solution☆

$\sf\blue {\implies 5x - \frac{1x + 1}{3} = 6( \frac{30x + 1}{30} )}$

[ Here we took the LCM of 1 & 30 and multiplied it by x and 1 in RHS ] ;

$\sf\implies { \frac{15x - x - 1}{3} = \frac{30x + 1}{5} }$

In LHS , we took the LCM of 1 and 3 and multiplied by 5x , -1x and 1.

( Now, it's looking a little bit scary xD xD )

$\sf\implies { \frac{14x - 1}{3} = \frac{30x + 1}{5}}$

$\sf\implies {5(14x - 1) = 3(30x + 1)}$

[ By cross multiplication ]

$\sf\implies {70x - 5 = 90x + 3}$

$\sf\implies {70x - 90x = 3 + 5}$

$\sf\implies { - 20x = 8}$

$\sf\implies {x = \frac{8}{ - 20} = - \frac{2}{5}}$

Yeah ! We got question's x after such tries , socho socho question bhi committed h tbhi to x hai iski xD xD :smirk:

${\sf{\purple{\boxed {∴ x = \frac{ - 2}{5}}}}}$
