Hi, I am having trouble understanding how to answer questions like this:
In general, the simplest way to handle equations with "rational fractions" is to multiply both sides by the least common denominator of all the fractions, thus elminating the fractions.
For example, to solve 3- x/5= 1/3, multiply both sides of the equation by 3(5)= 15 to get 3(15)- (x/5)(15)= (1/3)(15) or 45- 3x= 5. Then -3x= 5- 45= -40 and x= 40/3.
Warning, if your fractions have the "unknown", x, in a denominator, you must check any solutions in the original equation to see if any make a denominator 0. If so, that solution must be thrown out.
