For lab 3 part 1, you will be implementing the equation 3x+2y-z. The values for x, y, and z need to be first stored into registers named ex, why, and zee respectively using the RN directive and the data used should be defined by the terms exdata, whydata, and zeedata respectively using the EQU directive. For example, if the number #10 was to be moved into the "ex" register, #10 would be assigned to the symbol exdata. The result should be stored in a register named answer.
