-3,2n+4,8=-2*(1,2n+2,4) помогите решить
-3,2n+4.8 = -2*(1.2n+2.4)
-3.2n+4.8 = -2.4n - 4.8
4.8+4.8 = -2.4n+3.2n
9.6 = 0.8n
n = 9.6/0.8
n = 12
Проверяем:
-3.2*12+4.8 = -2*(1.2*12+2.4)
-38.4+4.8 = -33.6
Ответ: 12.
-3.2n+4.8=-2*(1.2n+2.4)
-3.2n+4.8=-2.4n-4.8
-3.2n+2.4n=-4.8-4.8
-0.8n=-9.6
n=-9.6:(-0.8)
n=12
ОТВЕТ: 12
