x/3 - 5/6 = 1/12 - x/2 / * 12
4x - 2 = 1 - 6x
4x + 6x = 1 + 2
10x = 3
x = 3/10
b)
7/9 + x/2 = 3/2 - x/18 / * 18
14 + 9x = 27 - x
9x + x = 27 - 14
10x = 13
x = 13/10 = 1 3/10
c)
x/2 - 3/4 = 7/8 + x/4 / * 8
4x - 6 = 7 + 2x
4x - 2x = 7 + 6
2x = 13
x = 13/2 = 6 1/2
d)
x/9 + 1/2 = 5/4 - x/6 + 1/12 / * 36
4x + 18 = 45 - 6x + 3
4x + 6x = 45 + 3 - 18
10x = 30
x = 30/10 = 3
