Решите уравнение 3/4-2/3+1=1/2x+1/6

3/4-2/3+1=9/12-8/12+1=13/12
1/2х+1/6=13/12
1/2х=13/12-1/6=13/12-2/12=11/12
Х=11/12:1/2=11/12*2/1=11/6=1 5/6
ответ: х=1 5/6

3/4-2/3+1=1/2x+1/6

3/4-2/3 = 9/12 - 8/12 = 1/12
1/12 + 1 = 1 1/12

1 1/12 = 1/2x + 1/6
1 1/12 - 1/6 = 1/2x
1 1/12 - 1/6 = 13/12 - 2/12 = 11/12

11/12 = 1/2x
x = 11/12:1/2 = 11/12*2/1 = 11/6= 1 5/6
