Question 281264: What is the answer to 2y-5x=7 ,to solve for x, and why?
The answer is opposite mine.
I worked this problem to this:
2y-5x=7 I subtracted -2y from both sides and got
-5x=7-2y then I divided -5 from both sides and got
7-2y/-5. The book's answer is 2y-7/5. How did they get an answer
opposite mine? Have I missed a mathematical principle?
