ЕленаФроленкова · Answer

(х - 83) + 316 = 425х - 83 = 425 - 316х - 83 = 109х = 109 + 83х = 192- - - - - - - - - - - -(600 - х) - 92 = 126600 - х = 126 + 92600 - х = 218х = 600 - 218х = 382- - - - - - - - - - - -253 - (х - 459) = 138х - 459 = 253 - 138х - 459 = 115х = 115 + 459х = 574- - - - - - - - - - - -502 - (217 - х) = 421217 - х = 502 - 421217 - х = 81х = 217 - 81х = 136- - - - - - - - - - - -871 - (х + 157) = 385х + 157 = 871 - 385х + 157 = 486х = 486 - 157х = 329...
