Question

помогите решить уравнения

Answer 1

$1)(127 + x) - 236 = 418 \\ x = 418 - 127 + 236 \\ x = 527$

$2)(492 - a) - 87 = 245 \\ - a = 245 - 492 + 87 \\ a = 160$

$3)(y - 246) + 154 = 300 \\ y = 300 + 246 - 154 \\ y = 392$

$4)745 - (x - 358) = 455 \\ - x = 455 - 745 - 358 \\ x = 648$

$5)304 - (543 - m) = 266 \\ m = 266 - 304 - 543 \\ m = - 581$

$6)789 - (x + 162) = 519 \\ - x = 519 - 789 + 162 \\ x = 108$

Answer 2

1) (127+х)-236=418
127+х-236=418
х=236+418-127
х=527
2)(492-а)-87=248
492-а-87=248
-а= 248+87-492
-а= -157/•(-1)
а=157
3)(у-246)+154=300
у-246+154=300
у=300-154+246
у=392
4)745-(х-358)=455
745-х+358=455
-х=455-745-358
-х=-648/•(-1)
х=648
5)304-(543-m)= 266
304-543+m=266
m=266+543-304
m=505
6) 789-(x+162)=519
789-x-162=519
-x=-108/•(-1)
x=108
