x = - 0,82
Пошаговое объяснение:
5 + 10 ( - 10х - 9) = - 3
5 - 100x - 90 = - 3
- 100x = - 3 - 5 + 90
- 100x = 82
x = - 82/100
x = - 0,82
Пошаговое объяснение:
5 + 10 ( - 10х - 9) = - 3
5 - 100x - 90 = - 3
- 100x = - 3 - 5 + 90
- 100x = 82
x = - 82/100
x = - 0,82
-100х=-3-5+90
-100х=82
х=82:(-100)
х=-0.82
