Answer 1

$frac{1}{3} x + 12 = x - frac{1}{6} x + 3$

$frac{1}{3} x + frac{1}{6} x - x = 3 - 12$

$frac{1}{2} - x = - 9$

$- frac{1}{2} x = - 9$

$x = 9 div frac{1}{2}$

$x = 18$

Ответ :

$18$

Answer 2

Решение:

$frac{1}{3}x + 12 = x - frac{1}{6}x + 3$

$frac{1}{3} x + 12 = x(1 - frac{1}{6} ) + 3$

$frac{1}{3} x + 12 = frac{5}{6}x +3$

$12 - 3 = frac{5}{6}x - frac{1}{3} x$

$9 = frac{1}{2}x$

$x = 9 div frac{1}{2}$

$x = 18$

Ответ: 18
