Odpowiedź:
d) x/6 - 1/6 = 1 |×6
x - 1 = 6
x = 7
e) -4x + 2 = x/3 |×3
-12x + 6 = x
6 = 13x
x = 6/13
f) 2/5(3-x) = -2 |×5
2(3-x) = -10
6 - 2x = -10
16 = 2x
x = 8
g) 3/4(2-3x) = -6 |×4
3(2-3x) = -24 |÷3
2-3x = - 8
3x = 10
x = 10/3
x = 3 1/3
h) x - 3 = (9-x)×5
x - 3 = 45 - 5x
6x = 48
i) 0,6 + x = 2(x+1)
x + 0,6 = 2x + 2
0,6 - 2 = x
x = - 1,4
