Ответ:
х=4\3
Пошаговое объяснение:
3\4х-6=3(2х-4)-1
3\4х-6=6х-12-1
0.75х-6х=-13+6
-5.25=-7
х=-7\(-5.25)
1 1/3
3/4х - 6 = 3(2х - 4) - 1
3/4х - 6 = 6х - 12 - 1
3/4х - 6 = 6х - 13
3/4х - 6х = -13 + 6
3/4х - 5 4/4х = -7
-5 1/4х = -7
-21/4х = -7
х = -7 : (-21/4)
х = -7 * (-4/21)
х = -1 * (-4/3)
х = 4/3
х = 1 1/3
