You can put this solution on YOUR website! assuming you mean
multiply every term by 10. Why 10? because it is the lowert common multiple of 5 and 2, so we can then cancel these denominators:
10y = -2*6x + 5*3
10y = -12x + 15
Not sure if this is what you mean by standard form or if "all positive terms" is standard form, which would be: 10y + 12x = 15
