    x - 30/100 = 315 x = 315 + 30/100 x = ?

    About which part, setting up the equation, reducing the equation, or dividing 315 by .7?

    Ok we can go through it slowly. First, we now that the product x was reduced by 30%. This means that originally we had some x and muliplied it by .3 to get the discount. Instead of doing this separately, we take 70% of the original x to find the discounted price. So that is .7x, which we know to be equal to 315. Then just divide .7 on each side (remember % is just a fancy way of saying that number per (divided by) cent (100).
