Question

12,4+2-X = 30,8 хелп​

Answer 1

Пошаговое объяснение:

$12.4 + 2 - x = 30.8$

$- x + 14.4 = 30.8$

$- x + (14.4 - 14.4) = 30.8 - 14.4$

$- x = 30.8 - 14.4$

$- x = 16.4$

$\frac{ - x}{ - 1} = - 16.4$

$x = - 16.4$

Answer 2

12,4+2-X = 30,8

14,4-х=30,8

х=14,4-30,8=-16,4

Ответ: х=-16,4
