Question 1 (Essay Worth 4 points)

One large jar and three small jars together can hold 14 ounces of jam. One large jar minus one small jar can hold 2 ounces of jam.

A matrix with 2 rows and 2 columns, where row 1 is 1 and 3 and row 2 is 1 and negative 1, is multiplied by matrix with 2 rows and 1 column, where row 1 is l and row 2 is s, equals a matrix with 2 rows and 1 column, where row 1 is 14 and row 2 is 2.

Use matrices to solve the equation and determine how many ounces of jam are in each type of jar. Show or explain all necessary steps.
