can someone check my answer for me please!
5x+6y=18 solve for y
6y=185
y=35/6x

ok

Close, except you have to subtract 5x from both sides. (You just subtracted 5 from the right side.)
5x + 6y = 18
Subtract 5x from both sides.
6y = 18  5x
Divide by 16
y = (185x)/6
or 3  (5/6)x
All right. I think you must have done it correctly, and you just forgot your x in the second step. Good job. :) 
Oops... that should say...
6y = 18  5x
Divide by 6 (not 16). 
okay so using y = (5/6)x + 3 how do i find the corresponding value for y when x = 12?

Simply plug in 12 for x...
y = (5/6)(12) + 3 = 10 + 3 = 7
