1) (the 2nd - 5) = 9 of the 2nd = 9+5 = 14 x = 14: 2 = 7 Proverk: (2 х 7 - 5) = 9 2) (0.6kh) = 7 x = 7: 6/10 = 7 x 10/6 = 70/6 Proverk: (6/10 x 70/6) = 7 3) (0.4kh - 1) = 2.2 0.4kh = 2.2 + 1 = 3.2 x = 3.2: 0.4 = 8 Proverk: (0.4 x 8 - 1) = 2.2 4) (0.5kh +3) = 5 0.5kh = 5 - 3 = 2 x = 2: 0.5 = 4 Proverk: (0.5 x 4 + 3) = 5 5) (2.5kh - 3) = 7 2.5kh = 7 + 3 = 10 x = 10: 2.5 = 4 Proverk: (2.5 x 4 - 3) = 7 6) (0.2 x + 7) = 8 0.2kh = 8-7 =1 x = 1: 0.2 = Proverk: (0.2 x 5 + 7) = 8 Even if brackets at you meant the module, the same decision.
