2x+5=19

2×=14

x=7

3x-9=15

3x=24

x=8

-3x+9=6

-3x=-3

x=1

-x+12-2x=-6

-3x+12=-6

-3x=-18

x=6

-17x-11=23

-17x=34

x= -2

5y+2+2y=-4-9y

7y+2=-4-9y

7y+9y=-4-2

16y=-6

$y = - \frac{6}{16} = - \frac{3}{8}$

-9(+4x-2)=-18

-36x+18=-18

-36x=-36

x=1

-5(-6+7x)=65

30-35x=65

-35x=35

x= -1

-9x-7+7x-3(2x+1)=-2

-9x-7+7x-6x-3=-2

-8x-10=-2

-8x=8

x= -1
