My way of approaching it...
1) Flip the side so your "=" sign is on the right (as you'd see in most problems)
2) We need to isolate y so let's try and pry that x out of there, using a little algebra we can just add it to both sides, and we're half-way done already!
That first 4x cancels out, giving us...
3) Now just one last step, we need y so divide it all by 5
That first 5 cancels out, giving us...
