achieved
To create the third equation, use the random numbers 2,3,4 and 5 to represent x,y,z, and the constant term respectively.
Solve the set of equations using the calculator and give a geometric interpretation of the solution. Write a general statement about the solution for the set of equations.
merit
To create the third equation add the cooefficients of the first equation to the second equation but keep the constant term of 5.
