I really find it hard to figure out how to structure my equation when faced with a word problem. I stumble a lot.

An example im working on If Y is your before-tax income, suppose that the government takes away 1/4y-10 as taxes. What was your pre-tax income if your after-tax income is $280.

So my brain tries junk like this.

x * 1/4Y - 10 = 280

Which I know isnt right. So any tips on how to structure word problems so I can more easily put them in equation format?
