Solve the following problem. Let's let marbles represent isotopes for us in this problem. A sample of marbles,
containing 2 different isotopes was massed. The mass of all the marbles (atoms) together was 141.6g. It was
determined that there were 42 marbles in total (some of marble isotope#1 and some of marble isotope#2).
Marble Isotope#1 has an individual mass of 2.6g and Marble Isotope#2 has an individual mass of 3.8g.
Determine the number of each type of Marble Isotope.
