Write 2.5x-0.3/3 =1/6y in standard form. Identify A, B, C. I know the answer is 2.5x - 5y = 3, but how?

2.5x - 0.3/3 = (1/6)y


mutiply each by 6


15x - .6 = y


15x - y = .6 to get rid of the fraction, multiply each by 5


75x - 5y = 3





Is the original problem this:


(2.5x - .3)/3 = (1/6)y


then the answer is 25x - 5y = 3





2.5x is not correct in the answer, if it's 2.5 in the original problem. Please check both. If your book has it that way both times, the book has an error.

Write 2.5x-0.3/3 =1/6y in standard form. Identify A, B, C. I know the answer is 2.5x - 5y = 3, but how?
