Question

Rezolvați ecuațiile:
1) 4–{–2+[–3–(2–x)+1]–5} = 3
2) 2+{3–[7–(x–5)–8]+6} = 1
3) 6–{4+[3–(x–1)+5]–6} = 8
4) 12–{6–[15– (2x –7)+5]–14} = 7
5) 21–{18–[15–(3x–2)–10]–13} = 2
6) 14–{12–[10–(8x–6)+7]+9} = 8
7) 32–{30–[28–(26x–24)–22]–20} = 0
8) 6–{8–[10–(12x–14)–16]–18} = 0
9) 4–{16–[12–(10x–15)–17]–9} = 17
10) 416–{10–[8–(3x–5)–7]–13} = 1
