3x-9y=9
Equation


-9y=-3x+9 Subtract 3x from both sides


y= (1)/(3)x-1 Divide by -9 on both sides


3x- 9( (1)/(3)x-1)=9 Plug in for y


9=9 Distribute -9 into the ( ) and simplify


3y=x+12
Equation


y= (1)/(3)x+4 Divide by 3 on both sides


3( (1)/(3)x+4)=x+12 Plug in for y


x+12=x+12 Simplify


2x-6y=12
Equation


-6y=-2x+12 Subtract 2x from both sides


y= (1)/(3)x-2 Divide by -6 on both sides


2x-6( (1)/(3)x-2 )=12 plug in for y


2x-2x+12=12 Distribute -6 into the ( )


12=12 Simplify
