Solving for ( y ):

Equation: ( 9x + 3y = 12 )
Rearranging: ( 3y = -9x + 12 )
Dividing by 3: ( y = -3x + 4 )
Equation: ( 4x + 2y = 20 )
Rearranging: ( 2y = -4x + 20 )
Dividing by 2: ( y = -2x + 10 )
Equation: ( 6x + y = 8 )
Rearranging: ( y = -6x + 8 )
Equation: ( -2x + y = 12 )
Rearranging: ( y = 2x + 12 )
Equation: ( 3x - 3y = 6 )
Rearranging: ( -3y = -3x + 6 )
Dividing by -3: ( y = x - 2 )

Summary of Answers:

( y = -3x + 4 )
( y = -2x + 10 )
( y = -6x + 8 )
( y = 2x + 12 )
( y = x - 2 )
