Пошаговое объяснение:
[tex]1.9 \times (x - 10.1) = 38.38[/tex]
[tex] \frac{1.9(x - 10.1)}{1.9} = \frac{38.38}{1.9} [/tex]
[tex]x - 10.1 = \frac{38.38}{1.9} [/tex]
[tex]x - 10.1 = 20.2[/tex]
[tex]x + ( - 10 + 10.1) = 10.1 + 20.2[/tex]
[tex]x = 20.2 + 10.1[/tex]
[tex]x = 30.3[/tex]
Ответ:
:)
1,9*(х-10,1)= 38,38
1,9х - 19,19=38,38
1,9х=38,38+19,19
1,9х=57,57
х= 57,57:1,9
х=30,3
Проверка:
1,9*(30,3-10,1)=38,38
1,9*20,2=38,38
38,38=38,38
