Suppose that you solve x 5 - x 2 = 1 by multiplying both sides by 20, rather than the
Chapter 6, Problem 122(choose chapter or problem)
Suppose that you solve \(\frac {x}{5} - \frac {x}{2} = 1\) by multiplying both sides by 20, rather than the least common denominator of \(\frac {x}{5}\) and \(\frac {x}{2}\) (namely, 10). Describe what happens. If you get the correct solution, why do you think we clear the equation of fractions by multiplying by the least common denominator?
