Answer 1

Приведем дроби к ОЗ=6. Получим

2*(2х+3)-(5х+13)+3*(5-2х)=36        ОЗ-8.   8х-(7х+1)=2*(4х+3)

4х+6-5х-13+15-6х=36                                  8х-7х-1 = 8х+6

-7х+8=36                                                        -7х=7

-7х=36-8                                                          х=-1 

-7х=28.  х=28:(-7).  х=-4
