Question

(1/16)2x-9=(1/4)x
пж решите

Answer 1

$\frac{1}{16} *2x-9= \frac{1}{4} x$
$\frac{1}{8}x-9= \frac{1}{4} x$
$\frac{1}{8}x- \frac{1}{4} x=9$
$\frac{1}{8}x- \frac{2}{8} x=9$
$- \frac{1}{8}x=9|*(-8)$
$x=-72$

Ответ: $x=-72$.

Answer 2

1/16 * 2x - 9= 1/4 x
1*2/16 x - 9 = 1/4 x
2/16 x - 9= 1/4 x
1/8 x - 9= 1/4 x
1/8 x - 1/4x = 9
(1/8)^1x - (1/4)^2 x = 9
1/8 x - 2/8 x= 9
- 1/8x = 9
x = 9: (-1/8)
x= - 72
