Question

у:0,03-8,5=16
х-0,64х=108​

Answer 1

Пошаговое объяснение:

1) y:0.03-8,5=16;

y:0.03=24,5;

y=0,725.

2) x-0,64x=108;

0,36x=108;

x=300.

Answer 2

1)$y \div 0.03 - 8.5 = 16$

$y \div \frac{3}{1000} - 8.5 = 16$

$y \div \frac{3}{1000 - \frac{17}{2} } = 16$

$y \times \frac{1000}{3} - \frac{17}{2} = 16$

$\frac{1000}{3} y - \frac{17}{2} = 16$

$2000y - 51 = 96$

$2000y = 147$

$y = \frac{147}{2000}$

2)-0,64x=108

0,36x=108

x=300
