-8/9x=-1
-3x=-2,7
-3/4x=-8/9
-100/8x=69 6/9
Równania proszę szybko na jutroooo

Answer 1

Odpowiedź:

0,3x=2,1

x = 7

-8/9x=-1

[tex]- \frac{8}{9x} = - 1[/tex]

- 8 = - 9x

[tex]x = \frac{8}{9}[/tex]

-3x=-2,7

x = - 0,9

-3/4x=-8/9

[tex]- \frac{3}{4x} = - \frac{8}{9}[/tex]

- 27 = -32x

[tex]x = \frac{32}{27}[/tex]

-100/8x=69 6/9

[tex]- \frac{100}{8x} = \frac{696}{9}[/tex]

- 900 = 5568x

[tex]x = -\frac{5568}{900}[/tex]

[tex]x = - \frac{464}{75}[/tex]
