1)х+1/2=2х-3/5+2 2)11-3х/4=х+13/6-х 3)5x+8/9 +x=7x+10/6
(x+1)/2 = (2*x-3)/5+2 11 - 0,75х - х - 13/6 +x = 0 х=2/3 записал коротко
x/2+1/2 = (2*x-3)/5+2 11 - 1,75 - 13/6 + x = 0
x/2+1/2 = 2*x/5-3/5+2 53/6 - 1,75x + x = 0
1/2 + x/2 = 7/5 + 2*x/5 53/6 - 0,75x = 0
x/2 = 9/10 + 2*x/5 x = 7
x/10 = 9/10
x = 9/10 / (1/10)
Получим ответ: x = 9
