subtract 2x from both sides:

Sorry,

I think I made a typo somewhere.

3y-15=2x-8 is the equation you need to put in the standard form.

Is the answer 2x-3y+7=0? (textbook answer) Why? -.-

Why is it NOT 2x-3y-7=0?

I'll admit I don't usually see this form for a line, but considering the expression as a multinomial it would be standard.
