Solve the system.
{ x + 2y = -9}
{5x + 10y = -45}
a. inconsistent (no solution)
b. (-9, 0)
c. (0, 0)
d. y=-x/2- 9, where x is any real number
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

  x +  2y =  -9,    (1)
 5x + 10y = -45.    (2)

y = %28-9+-+x%29%2F2.

Two equations are dependent, and the system has infinitely many solutions.

NO ONE OPTION a), b), c) d) fits.
