НСК=8
18х-14-9х-13-12+4х=0
13х=39; х=3
(9х - 7)/4 - (9х + 13)/8 = (3-х)/2 | * 8
2(9х - 7) - (9х + 13) = 4(3 - х)
18х - 14 - 9х - 13 = 12 - 4х
18х - 9х + 4х = 12 + 14 + 13
13х = 39
х = 39 : 13
х = 3

Объяснение:
(9х - 7)/4 - (9х + 13)/8 = (3-х)/2 | * 8
2(9х - 7) - (9х + 13) = 4(3 - х)
18х - 14 - 9х - 13 = 12 - 4х
18х - 9х + 4х = 12 + 14 + 13
13х = 39
х = 39 : 13
х = 3
