A jeweler had a fixed amount of gold to make bracelets and necklaces. The amount of gold in each bracelet is 6 grams and the amount of gold in each necklace is 16 grams,
The jeweler used 178 grams of gold and made 7 more necklaces than bracelets. Write
a system of equations that could be used to determine the number of bracelets made
and the number of necklaces made. Define the variables that you use to write the
system.
