2. Rozwiąż równania. a) ⅓ x - 2 = x + 2 b) 1 -⅗ 6/7x = 4/7 c) 6 ( ¼x - 2 ) = 18 d) x/6 - 1/6 = 1 e) -2( 2x - 1) = x/3 f) ⅖ ( 3 - x) = -2 g) ¾ (2 - 3x) = -6 h) ⅕ (x-3) = 9 - x czytelnie !

a) ⅓ x - x = 2 +2 - ⅔x = 4 x = -6 b) -6/7x = 4/7 - 1 /:(-6/7) x = 1/2 c) 3/2x - 12 = 18 3/2x = 18+12 x = 20 d) x/6 = 1 +1/6 x/6 = 7/6 x = 7 e) -4x +2 = x/3 -4x - x/3 = -2 - 13/3x = -2 x = 6/13 f) 6/5 - 2/5x = -2 -2/5x = -2 - 6/5 -2/5x = -16/5 x = 8 g) 3/2 - 9/4x = -6 -9/4x = -6 - 3/2 -9/4x = -15/2 x = 10/3 h) 1/5x - 3/5 = 9-x 1/5x + x = 9 + 3/5 6/5x = 48/5 x = 8
