Question

Как решить
475-(x-671)=325
403-(634-a)=366
987-(x+364)=519

Answer 1

475-(х-651)= 325
х-651=475-325
×-651=150
×=651+150
×=801

403-(634-а)=366
634-а=403-366
634-а=37
а=634-37
а=597

987-(×+364)=519
987-519=468
468+364=832
×=832

Answer 2

1)475-(x-671)=325
x-671=475+325
x-671=800
x=800+671
x=1471
475-(1471-671)=325
2)403-(634-a)=366
634-a=403-366
634-a=37
a=634-37
a=597
403-(634-597)=366
3)987-(x+364)=519
x+364=987-519
x+364=468
x=468-364
x=104
987-(104+364)=519
