Our goal is to perform algebraic operations so that the variables appear in the numerator. By doing so, the leftover equation to deal with is usually. Then, you�ll see how to solve an equation containing rational expressions with unlike denominators. Note any value of the variable that would make any denominator zero. In fact, we will eliminate all denominators by multiplying both sides of the equation by the least common denominator (lcd). Clear the fractions by multiplying both sides of the equation by the lcd.
