What is the exposure? North, south, east west?
Any side with a southern exposure, You can try to plant annuals this year that might compete with the weeds..
morning glory(hot weather) or sweet pea (cool weather) are both fast growing vines that may help smother the weeds on the sunny side of the yard to sustain your gains. but it's not a long term solution, and you must cut everything down before the weeds go to seed
