Решите уравнения:
х-350= 350
а*52= 156
с:50= 250
в+350= 478

х-350= 350х= 350+350х= 700__________700-350=350       350=350а*52= 156а= 156:52а= 3_________3*52= 156   156=156с:50= 250с= 250*50с= 12500________12500:50= 250          250=250в+350= 478в= 478-350в= 128____________128+350= 478        478= 478

1. x = 350+350 = 7002. a = 156/52 = 33. c = 250*50 = 125004. b = 478-350 = 128
