Răspuns:

[(c+97-100):5+(70+168×5:8)]-230=10

(c+97-100):5+(70+168×5:8)=10+230

(c+97-100):5+(70+168×5:8)=240

(c+97-100):5+(70+840:8)=240

(c+97-100):5=240-(70+840:8)

(c+97-100):5=240-70-840:8)

(c+97-100):5=170-840:8

c+97-100=(170-840:8)×5

c=(170-840:8)×5+100-97

c=(170-840:8)×5+3

c=(170-840:8)×5+3

c=(170-105)×5+3

c=65×5+3

c=325+3

c=328
