Part I: Solving simultaneous equations using the matrix package You will use the following files: . matrix.jar documentation found in javadoc > Matrix o e.bat //for those unable to set the PATH and CLASSPATH environment variables . Consider the following set of equations: 1.6x1 + 2.4x2 - 3.7x3-22.10 17.6x1 5.6x2 0.05x3--4.35 -2x 2x2 +25.3x3 -233.70 These equations can be represented in matrix form as Ax b where A is a 3x3 matrix of the coefficients, x is a 3xl matrix of the unknown values, and b is a 3xl matrix of the right-hand side (RHS). This matrix equation can be inverted to solve for the unknowns, x - Ab. Use the matrix package (in the jar file, don't extract the files) and the associated external documentation to solve the above system of equations. You will need to use the import statement and -classpath (or-cp) to compile and run so that you can access the classes in the jar file. You may want to consider using a batch file to speed up compiling and running with a custom classpath. Declare your matrix variables to be type MatrixOperationsInterface. Call your driver Equations.java
