Solve: 

-22 = 14 - 9 x 

• x = - 4

• x = 4

• x = 2

• x = - 2

13 y = -12 y + 100

• y = 100

• y = -100

• y = 4

• y = - 4

30 = 6 ( 8 + y )

• y = 3

• y = -3

• y = 18

• y = -18

 $\frac{y}{4}\ -\ 3\ =\ 13$  

• y = 16

•  y = 4

• y = 64

• y = 40

 $\frac{3x\ +\ 9}{4}=\ 6$  

• x = 1

• x = 8

• x = -5

• x = 5

 $\frac{5}{6}\ =\frac{x}{30}$  

• x = 150

• x = 29

• x = 36

• x = 25

 $\frac{4}{x\ -\ 2}=\frac{10}{25}$  

• x = 12

• x = 20

• x = 8

• x = 4
