868. Решите уравнение: 1) x + 4,83 = 9; 2) 43,78 - x = 5,384; 3) x - 14,852 = 15,148; 4) 2,395 + x = 10.

Решение: 1) \(x + 4,83 = 9\) => \(x = 9 - 4,83\) => \(x = 4,17\) 2) \(43,78 - x = 5,384\) => \(x = 43,78 - 5,384\) => \(x = 38,396\) 3) \(x - 14,852 = 15,148\) => \(x = 15,148 + 14,852\) => \(x = 30\) 4) \(2,395 + x = 10\) => \(x = 10 - 2,395\) => \(x = 7,605\)
