Some (linear) equations with fractions - pre-algebra lesson
These equations involve fractions and parenthesis. Sometimes we need to use the distributive property and multiply out the brackets (parentheses); sometimes multiplying both sides by the reciprocal of the fraction is quicker.
Lastly, we need to find a real-world situation that matches the given equation 5(p - 3) = $15.50. Naturally, p could be a price of a product that is discounted by $3. Then someone buys 5 of those products and the total bill is $15.50.
