First, combine like terms.
12y+6=6y+12 turns into
12y-6y=12-6, which is
6y=6. Now divide both sides by 6.
y=1
now do a quick check (cause that's always a good idea).
12(1)+6=6(1)+12
12+6=6+12

Answer:
The general equation of the lines that are perpendicular is:

b can by any number.
Step-by-step explanation:
The equation of a line is given by:

where m is the slope and b is the intercept
The equation of a perpendicular line to the previuos one is:

That means that the slope of a perpendicular line is inverse and sign opposite to the other line.
Hence, the equation given is:

m would be:
m=1
So the perpendicular slope would be:

The general equation of the lines that are perpendicular to y=x+3 is:

b can be any number
In attached picture:
y=x+3 is the red line
y=-x+b is the blue line
