Question

помогите найти (3x+41)•28-248=3000

Answer 1

(3х + 41) * 28 - 248 = 3.000
(3х + 41) * 28 = 3.000 + 248
(3х + 41) * 28 = 3.248
3х + 41 = 3.248 : 28
3х + 41 = 116
3х = 116 - 41
3х = 75
х = 75 : 3
х = 25
проверка:
(3 * 25 + 41) * 28 - 248 = 3.000
(75 + 41) * 28 - 248 = 3.000
116 * 28 - 248 = 3.000
3.248 - 248 = 3.000
3.000 = 3.000
