2. Решите уравнения: 1) 395-(27x-26x)=189;
2) (73x–72x) - 89=214
3) 127+(95x–94x)=212;
4) (83x-82x)+317=502.​

1) 395 - 27x + 26x = 189

-27x + 26x = 189 - 395

-x = -206

x = 206

2) (73х - 72х) - 89 = 214

х - 89 = 214

х = 214 + 89

х = 303

3)127+(95х-94х)=212

127+ x=212

x=212-127

х=85

4)

(83х-82х)+317=502

х+317=502

х=502-317

х=185
