Answer: x<=1
Explanation: you first move the constant to the right, making the equation turn into -13x>=-1-12. Next, you calculate -1-12 which is -13, and plug that into the equation to make -13x>=-13. Last but not least, you divide -13 on both sides to leave x by itself, and flip the inequality sign. Then you get your answer: x<=1. Hope this helps! :)
