1.


Which of the following systems is equivalent to the given system?


2/3 x - y = 2

x + 1/2 y = -3

2x - 3y = 6 and 2x + y = 6

6x - 3y = 6 and 2x + y = 10

2x - 3y = 6 and 2x + y = -6



2.


Given the system of equations, what is the solution?


x + 3y = 5

x - 3y = -1

{(-4, -3)}

{(2, 1)}

{(-2, 3)}
