Question

Всем привет не могу решить уравнение:(3 1/2 x-1/4)*8=3

Answer 1

3 12 х - 14 = 3:8
3 12 х - 14 = 38
3 12 х = 38 +14
3 12 х = 38 + 28
3 12 х = 58
х= 58 : 3 12
х= 58 * 27
х= 5 28

Answer 2

(3 1/2х - 1/4)* 8 = 3
7/2х - 1/4 = 3/8
7/2х = 3/8 + 1/4
7/2х = 3/8 + 2/8
7/2х = 5/8
х = 5/8 : 7/2
х = 5/28
