Решите уравнения: а) 3х+5х+96=1568 б) 357z-149z-1843=11469 Заранее спасибо*)))

3Х+5Х+96=1568                                      357z-149z-1843=11469

8Х=1568-96                                             208z=11469+1843   

8Х=1472                                                   208z=13312

Х= 1472делим8                                       z= 13312делим208

 Х=184                                                     z=64

а) 3х+5х+96=1 568

3х+5х=1 568-96

8х=1 472

х=1 472:8

х=184

б) 357z-149z-1 843=11 469

357z-149z=11 469+1 843

208z=2 989

z=13 312:208

z=64
