Первое:
[tex](x - 18.2) + 3.8 = 15.6 \\ x - 18.2 = 15.6 - 3.8 \\ x - 18.2 = 11.8 \\ x = 11.8 + 18.2 \\ x = 30[/tex]
Второе:
[tex]13.3 + 13.3 + 0.9 + 13.3 + 0.9 - 2.9 = \\ 38.8[/tex]
надеюсь помог)
Пошаговое объяснение:
(�−18.2)+3.8=15.6�−18.2=15.6−3.8�−18.2=11.8�=11.8+18.2�=30(x−18.2)+3.8=15.6x−18.2=15.6−3.8x−18.2=11.8x=11.8+18.2x=30
