Question

Реши уравнение 3000:(x-12)=75*5

Answer 1

$\frac{3000}{\left(x-12\right)}=75\cdot \:5\\\frac{3000}{x-12}=75\cdot \:5\\\frac{3000}{x-12}\left(x-12\right)=75\cdot \:5\left(x-12\right)\\3000=375\left(x-12\right)\\375\left(x-12\right)=3000\\\frac{375\left(x-12\right)}{375}=\frac{3000}{375}\\x-12=8\\x-12+12=8+12\\x=20$

Answer 2

x = $\frac{24}{5}$

Пошаговое объяснение:

3000:(x-12)=75*5

$\frac{3000}{x}$-250=375

$\frac{3000}{x}$=625

x = $\frac{24}{5}$
