Помогите упростить уравнения (8c-1)*5=235 и (4n+12):8=136
(8c-1)*5=235 8c-1=235:5 8с=47+1 8с=48 с=48:8 с=6 (4n+12):8=136 4n+12=136*8 4n=1088-12 4n=1076 n=1076:4 n=269
8c - 1 = 235:5 8c - 1 = 47 8c = 47 + 1 8c = 48 c = 48:8 c = 6 4n + 12 = 136*8 4n + 12 = 1088 4n = 1088 - 12 4n = 1076 n = 1076:4 n = 269
