Решите Уравнения:

1)8-9х = 10х +10

2) 3-9х= 8х - 7 

3)-3-8х = 4х+7

4)10-7х = 7 х - 7

5)7-8 х = 7х + 6

Answer 1

1)8-9х = 10х +10

-9х-10х=10-8

-19х=2

х=-2/19

2) 3-9х= 8х - 7 

-9х-8х=-7-3

-17х=-10

х=10/17

3)-3-8х = 4х+7

-8х-4х=7+3

-12х=10

х=10/12=5/6

4)10-7х = 7 х - 7

-7х-7х=-7-10

-14х=-17

х=17/14

5)7-8 х = 7х + 6

-8х-7х=6-7

-15х=-1

х=1/15
