Question

5х-4/2-2х-1/3=-1/5(х-29)
3+2х/3-(х+1/5-1-х/6)=1
2x+1/3-3+4x/9+0.5=x
/=дробная черта

х-29 --- под дробью??

Answer 1

(3+2х)/3 -( (х+1)/5 - (1-х)/6)=1
(3+2х)/3 -( (6х+6-5+5х)/30)=1
(3+2х)/3 - (11х+1)/30)=1
10(3+2х)-11х-1=30
30+20х-11х-1=30
9х=30-29
9х=1
х=1/9

(2х+1)/3 - (3+4х)/9 +0,5=х
3(2х+1) -3 -4х+0,5*9=9х
6х+3-3-4х+4,5=9х
9х-2х=4,5
7х=4,5
х=4 1/2 :7
х=9/2 * 1/7
х=9/14
