Question

решите уровнение (19х+62):15=13

Answer 1

(19х + 62):15 = 13
19х + 62 = 13*15
19х + 62 = 195
19х = 195-62
19х = 133
Х = 133:19
Х = 7
--------
(19*7 +62):15 = 13
(133+62):15 = 13
195:15 = 13
13 = 13

Answer 2

=
19х+62=13*15
19х+62=195
19х=195-62
19х=133
х=133:19
х=7

Проверяем:
(19х7+62):15=13
(133+62):15=13
195:15=13
