​

1)Y=1

1 = 2/3 + 6x

6x = 1-2/3

6x=1/3

x=1/3÷6

x = 1/3*1/6 = 1/18

2) Y=-1

-1=2/3+6x

6x=-1-2/3

6x=-5/3

x=-5/3÷6

x=-5/3*1/6=-5/18

3) Y = -2/3

-2/3 = 2/3+6x

6x = -2/3-2/3

6x=-4/3

x=-4/3÷6

x = -4/3*1/6 = -4/18 = -2/9

4)Y = 5

5 = 2/3 + 6x

6x = 5-2/3

6x = 13/3

x=13/3÷6

x = 13/3 * 1/6 = 13/18
