What are we solving for?

if it's Y then Y =3x-3 or Y = 3(x-1)
if it's X then X =  (1/3)y +1

i gave you the answer but you probably won't be able to explain to why
so here are the steps.  

Also to move a number such as 12 or 4y to the other side equal sign just change the sign of the value
ex: 12 becames -12 or -4y becames +4y
hope this helps

solve for y

2(2y +9) = 3(4x +2)
4y + 18 = 12 x + 6
4y = 12 x +6 - 18
y = (12x / 4) + (6 - 18 )/4
y = 3x - (12 / 4)
y = 3x - 3 = 3 (x - 1)

as for solve for x

2(2y +9) = 3(4x +2)
4y + 18 = 12x + 6
4y + 18 - 6 = 12x
4y + 12 = 12x or 12x = 4y +12
x = (4/12)y + 12/12
x = (1/3)y + 1
