Question

X - X/10 -2X/5 - 15000 -21000=13000​

Answer 1

$\sf\small{x - \frac{x}{10} - \frac{2x}{5} - 15000 - 21000 = 13000}$

$\sf\small \pmb\rightarrowtail{x - \frac{x}{10} - \frac{2x}{5} - 36000 = 13000}$

$\sf\small\pmb\rightarrowtail{x \times10 - \frac{x}{10}\times10 \times \frac{2x}{5} \times 10 - 36000 \times 10 = 13000 \times 10}$

$\sf\small \pmb\rightarrowtail{5x - 360000 = 130000}$

$\sf\small \pmb\rightarrowtail{5x - 360000 + 360000 = 130000 + 13000}$

$\sf\small \pmb\rightarrowtail{5x = 490000}$

$\sf\small \pmb\rightarrowtail{ \frac{5x}{5} = \frac{490000}{5}}$

x = 98000

Answer 2

$\huge\boxed{x=98000}$
