1. Create two variables by assigning 4 and 5 to x and y. Assign the value of x + y to
the variable z. What two statements do this correctly?
a. 4 = x; 5 = y; x+y = z
b. x = 4; y = 5; z = x+y
c. x = 4; 5 = y; z = x+y
2.Determine the values of x,y,and z for the following set of linear algebraic equations:
