Question

Найди корень каждого уравнения
X+14=92 619+x=8209
X-6209=12804
8002-x=295

Answer 1

$x = 92 - 14 = 78 \\ x = 8209 - 619 = 7590 \\ x = 12804 + 6209 = 19013$
$x = 8002 - 295 = 7707$

Answer 2

Х+14=92
Х=92-14
Х=78
________
78+14=92
92=92


619+х=8209
Х=8209-619
Х=7590
_________
619+7590=8209
8209=8209

Х-6209=12804
Х=12804+6209
Х=19013
________
19013-6209=12804
12804=12804

8002-х=295
Х=8002-295
Х=7707
_________
8002-7707=295
295=295
