14x+5-25x=6x+39
-9x-15+8x=13x+33​

Пошаговое объяснение:

14x+5-25x=6x+39

14x-25x-6x=39-5

-17x=34

x=-2

-9x-15+8x=13x+33​

-9x+8x-13x=33+15

-14x=48

x=-48/14

x=-3 6/14

x= -3 3/7

1)14х+5-25х=6х+39

-11х+5=6х+39

-11х-6х=39-5

-17х=34

х= - 2

2) - 9х-15+8х=13х+33

- х-15=13х+33

- х-13х=33+15

- 14х=48

х= - 48/14= - 24/7= - 3 3/7
