What is y=−29x 3 in standard form using integers?
cupoosta [38]
<span>add 2/9x to both sides, if you do that you get 2/9x+y=3. If you want to simplify it multiply everything by the denominator, in this case, 9 so then you would have 2x+9y=27 

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
