Відповідь:

Покрокове пояснення:

1)0=0 це означає що х може бути будь_яким числом

2)9х-3=х+5

відомі в один бік, а не відомі в інший

9х-х=5+3

8х=8

х=1

3) зводимо до одного знаменника 6, тоді перший дріб множимо на 3, другий дріб на 4 і третій на 2

3(х+1)+4х=2(х-2)

виконуємо множення

3х+3+4х=2х-4

відомі в один бік, а не відомі в інший

3х+4х-2х=-4-3

5х=-7

х=-7/5

виділяємо цілу частину

х=-1  2/5
