Express in simplest(sp) form:
%28%28x%2B7%29%2F5%29%2B%28%283-x%29%2F4%29 When adding/subtracting fractions, you'll need to find the common denominator. In this case it's (5)*(4) = 20.
%284%28x%2B7%29%2F%284%2A5%29%29%2B%285%283-x%29%2F%284%2A5%29%29 Simplify.
%28%284x%2B28%29%2F20%29%2B%28%2815-5x%29%2F20%29
highlight%28%28-x%2B43%29%2F20%29
