Question

32 + (c×8)= 112
86 – (40 : x) = 78
помогите пожалуйста​

Answer 1

32 + (с × 8) = 112

с × 8 = 112 - 32 = 80

с = 80 ÷ 8 = 10

86 - (40 ÷ х) = 78

40 ÷ х = 86 - 78 = 8

х = 40 ÷ 8 = 5

Answer 2

Ответ:

$c = 10 \: \: \: \: x = 5$

Пошаговое объяснение:

$32 + (c \times 8) = 112 \\ c \times 8 = 112 - 32 \\ c \times 8 = 80 \\ c = 80 \div 8 \\ c = 10 \\ \\ 86 - (40 \div x) = 78 \\ - 40 \div x = 78 - 86 \\ - 40 \div x = - 8 \\ x = - 40 \div ( - 8) \\ x = 5$
