x = - 5,65
Пошаговое объяснение:
// Записываем уравнение
12x+4,5=10x-6,8
// перекидываем числа с иксами на одну сторону, а простые числа на другую и меняем их знаки
12x-10x=-4,5-6,8
// производим с ними действия
2x = -11,3
// по факту, мы получаем простецкое уравнение, которое работает по правилу: "Чтобы найти неизвестную часть, надо из целого вычесть известную часть" это если к иксу прибавляем или вычитаем. А если у нас умножение то мы Целую часть делим на известную
x = -11,3 : 2
x = - 5,65

12х-10х = -6,8-4,5
2х = -11,3
х = -11,3/2
х = -5,65
