Two systems of equations are given below For each system cho

Two systems of equations are given below. For each system, choose the best description of its solution. If applicable, give the solution.

1) -x + 3y = - 9

x - 3y = 9

solving the two equations

adding equation 1 and 2

-x + 3y = - 9

x - 3y = 9

-----------------------

0 = 0

hence , in such condition system of equations have infinitely many solutions

2) -x + 3y = 6

x - 3y = 6

adding 2 equations we get

0 = 12

in such condition the system of equation has no solution
